Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15546, here are decompositions:

  • 5 + 15541 = 15546
  • 19 + 15527 = 15546
  • 53 + 15493 = 15546
  • 73 + 15473 = 15546
  • 79 + 15467 = 15546
  • 103 + 15443 = 15546
  • 107 + 15439 = 15546
  • 163 + 15383 = 15546

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15546 first appears in π at position 127,209 of the decimal expansion (the 127,209ordinal-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.
