Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19116, here are decompositions:

  • 29 + 19087 = 19116
  • 37 + 19079 = 19116
  • 43 + 19073 = 19116
  • 47 + 19069 = 19116
  • 79 + 19037 = 19116
  • 103 + 19013 = 19116
  • 107 + 19009 = 19116
  • 137 + 18979 = 19116

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19116 first appears in π at position 108,385 of the decimal expansion (the 108,385ordinal-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.
