Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531712, here are decompositions:

  • 11 + 531701 = 531712
  • 23 + 531689 = 531712
  • 89 + 531623 = 531712
  • 101 + 531611 = 531712
  • 131 + 531581 = 531712
  • 191 + 531521 = 531712
  • 353 + 531359 = 531712
  • 359 + 531353 = 531712

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 531,712 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 531712 first appears in π at position 858,070 of the decimal expansion (the 858,070ordinal-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.
