Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19112, here are decompositions:

  • 31 + 19081 = 19112
  • 43 + 19069 = 19112
  • 61 + 19051 = 19112
  • 103 + 19009 = 19112
  • 139 + 18973 = 19112
  • 193 + 18919 = 19112
  • 199 + 18913 = 19112
  • 421 + 18691 = 19112

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19112 first appears in π at position 20,332 of the decimal expansion (the 20,332ordinal-suffix:nd 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.
