Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13742, here are decompositions:

  • 13 + 13729 = 13742
  • 19 + 13723 = 13742
  • 31 + 13711 = 13742
  • 61 + 13681 = 13742
  • 73 + 13669 = 13742
  • 109 + 13633 = 13742
  • 151 + 13591 = 13742
  • 229 + 13513 = 13742

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13742 first appears in π at position 108,826 of the decimal expansion (the 108,826ordinal-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.
