Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 537686, here are decompositions:

  • 7 + 537679 = 537686
  • 13 + 537673 = 537686
  • 103 + 537583 = 537686
  • 139 + 537547 = 537686
  • 283 + 537403 = 537686
  • 307 + 537379 = 537686
  • 313 + 537373 = 537686
  • 379 + 537307 = 537686

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 537,686 and was likely granted around 1894.

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

Position in π

The digit sequence 537686 first appears in π at position 195,008 of the decimal expansion (the 195,008ordinal-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.
