Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19310, here are decompositions:

  • 37 + 19273 = 19310
  • 43 + 19267 = 19310
  • 61 + 19249 = 19310
  • 73 + 19237 = 19310
  • 79 + 19231 = 19310
  • 97 + 19213 = 19310
  • 103 + 19207 = 19310
  • 127 + 19183 = 19310

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19310 first appears in π at position 40,747 of the decimal expansion (the 40,747ordinal-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.
