Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51582, here are decompositions:

  • 5 + 51577 = 51582
  • 19 + 51563 = 51582
  • 31 + 51551 = 51582
  • 43 + 51539 = 51582
  • 61 + 51521 = 51582
  • 71 + 51511 = 51582
  • 79 + 51503 = 51582
  • 101 + 51481 = 51582

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 51582 first appears in π at position 99,798 of the decimal expansion (the 99,798ordinal-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.
