Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15770, here are decompositions:

  • 3 + 15767 = 15770
  • 31 + 15739 = 15770
  • 37 + 15733 = 15770
  • 43 + 15727 = 15770
  • 103 + 15667 = 15770
  • 109 + 15661 = 15770
  • 127 + 15643 = 15770
  • 151 + 15619 = 15770

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15770 first appears in π at position 3,280 of the decimal expansion (the 3,280ordinal-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.
