Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19364, here are decompositions:

  • 31 + 19333 = 19364
  • 97 + 19267 = 19364
  • 127 + 19237 = 19364
  • 151 + 19213 = 19364
  • 157 + 19207 = 19364
  • 181 + 19183 = 19364
  • 223 + 19141 = 19364
  • 277 + 19087 = 19364

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19364 first appears in π at position 67,909 of the decimal expansion (the 67,909ordinal-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.
