Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511850, here are decompositions:

  • 7 + 511843 = 511850
  • 19 + 511831 = 511850
  • 127 + 511723 = 511850
  • 139 + 511711 = 511850
  • 181 + 511669 = 511850
  • 223 + 511627 = 511850
  • 271 + 511579 = 511850
  • 277 + 511573 = 511850

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 511,850 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 511850 first appears in π at position 357,929 of the decimal expansion (the 357,929ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
