Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19304, here are decompositions:

  • 3 + 19301 = 19304
  • 31 + 19273 = 19304
  • 37 + 19267 = 19304
  • 67 + 19237 = 19304
  • 73 + 19231 = 19304
  • 97 + 19207 = 19304
  • 163 + 19141 = 19304
  • 223 + 19081 = 19304

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19304 first appears in π at position 8,665 of the decimal expansion (the 8,665ordinal-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.
