Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15430, here are decompositions:

  • 3 + 15427 = 15430
  • 17 + 15413 = 15430
  • 29 + 15401 = 15430
  • 47 + 15383 = 15430
  • 53 + 15377 = 15430
  • 71 + 15359 = 15430
  • 101 + 15329 = 15430
  • 131 + 15299 = 15430

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15430 first appears in π at position 44,799 of the decimal expansion (the 44,799ordinal-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.
