Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511186, here are decompositions:

  • 17 + 511169 = 511186
  • 23 + 511163 = 511186
  • 167 + 511019 = 511186
  • 173 + 511013 = 511186
  • 197 + 510989 = 511186
  • 359 + 510827 = 511186
  • 383 + 510803 = 511186
  • 419 + 510767 = 511186

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 511,186 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 511186 first appears in π at position 81,082 of the decimal expansion (the 81,082ordinal-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.
