Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19340, here are decompositions:

  • 7 + 19333 = 19340
  • 31 + 19309 = 19340
  • 67 + 19273 = 19340
  • 73 + 19267 = 19340
  • 103 + 19237 = 19340
  • 109 + 19231 = 19340
  • 127 + 19213 = 19340
  • 157 + 19183 = 19340

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19340 first appears in π at position 68,561 of the decimal expansion (the 68,561ordinal-suffix:st 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.
