Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531422, here are decompositions:

  • 79 + 531343 = 531422
  • 193 + 531229 = 531422
  • 379 + 531043 = 531422
  • 433 + 530989 = 531422
  • 439 + 530983 = 531422
  • 571 + 530851 = 531422
  • 691 + 530731 = 531422
  • 709 + 530713 = 531422

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 531,422 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 531422 first appears in π at position 97,338 of the decimal expansion (the 97,338ordinal-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.
