Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511386, here are decompositions:

  • 53 + 511333 = 511386
  • 59 + 511327 = 511386
  • 89 + 511297 = 511386
  • 97 + 511289 = 511386
  • 107 + 511279 = 511386
  • 149 + 511237 = 511386
  • 163 + 511223 = 511386
  • 173 + 511213 = 511386

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 511,386 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 511386 first appears in π at position 31,662 of the decimal expansion (the 31,662ordinal-suffix:nd 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.
