Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531502, here are decompositions:

  • 5 + 531497 = 531502
  • 149 + 531353 = 531502
  • 239 + 531263 = 531502
  • 263 + 531239 = 531502
  • 359 + 531143 = 531502
  • 401 + 531101 = 531502
  • 431 + 531071 = 531502
  • 479 + 531023 = 531502

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 531,502 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 531502 first appears in π at position 215,130 of the decimal expansion (the 215,130ordinal-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.
