Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19368, here are decompositions:

  • 59 + 19309 = 19368
  • 67 + 19301 = 19368
  • 79 + 19289 = 19368
  • 101 + 19267 = 19368
  • 109 + 19259 = 19368
  • 131 + 19237 = 19368
  • 137 + 19231 = 19368
  • 149 + 19219 = 19368

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19368 first appears in π at position 24,811 of the decimal expansion (the 24,811ordinal-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.
