Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531282, here are decompositions:

  • 19 + 531263 = 531282
  • 29 + 531253 = 531282
  • 43 + 531239 = 531282
  • 53 + 531229 = 531282
  • 79 + 531203 = 531282
  • 109 + 531173 = 531282
  • 113 + 531169 = 531282
  • 139 + 531143 = 531282

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 531,282 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 531282 first appears in π at position 740,639 of the decimal expansion (the 740,639ordinal-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.
