Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531610, here are decompositions:

  • 29 + 531581 = 531610
  • 41 + 531569 = 531610
  • 59 + 531551 = 531610
  • 89 + 531521 = 531610
  • 113 + 531497 = 531610
  • 227 + 531383 = 531610
  • 251 + 531359 = 531610
  • 257 + 531353 = 531610

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 531,610 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 531610 first appears in π at position 274,354 of the decimal expansion (the 274,354ordinal-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.
