Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502538, here are decompositions:

  • 31 + 502507 = 502538
  • 37 + 502501 = 502538
  • 97 + 502441 = 502538
  • 109 + 502429 = 502538
  • 199 + 502339 = 502538
  • 277 + 502261 = 502538
  • 367 + 502171 = 502538
  • 397 + 502141 = 502538

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 502,538 and was likely granted around 1893.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 502538 first appears in π at position 289,958 of the decimal expansion (the 289,958ordinal-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.
