Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15184, here are decompositions:

  • 11 + 15173 = 15184
  • 23 + 15161 = 15184
  • 47 + 15137 = 15184
  • 53 + 15131 = 15184
  • 83 + 15101 = 15184
  • 101 + 15083 = 15184
  • 107 + 15077 = 15184
  • 131 + 15053 = 15184

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15184 first appears in π at position 129,400 of the decimal expansion (the 129,400ordinal-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.
