Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51508, here are decompositions:

  • 5 + 51503 = 51508
  • 29 + 51479 = 51508
  • 47 + 51461 = 51508
  • 59 + 51449 = 51508
  • 71 + 51437 = 51508
  • 89 + 51419 = 51508
  • 101 + 51407 = 51508
  • 167 + 51341 = 51508

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51508 first appears in π at position 504,792 of the decimal expansion (the 504,792ordinal-suffix:nd 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.
