Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10520, here are decompositions:

  • 7 + 10513 = 10520
  • 19 + 10501 = 10520
  • 43 + 10477 = 10520
  • 61 + 10459 = 10520
  • 67 + 10453 = 10520
  • 151 + 10369 = 10520
  • 163 + 10357 = 10520
  • 199 + 10321 = 10520

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 10520 first appears in π at position 154,984 of the decimal expansion (the 154,984ordinal-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.
