Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26320, here are decompositions:

  • 3 + 26317 = 26320
  • 11 + 26309 = 26320
  • 23 + 26297 = 26320
  • 53 + 26267 = 26320
  • 59 + 26261 = 26320
  • 71 + 26249 = 26320
  • 83 + 26237 = 26320
  • 131 + 26189 = 26320

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26320 first appears in π at position 316,452 of the decimal expansion (the 316,452ordinal-suffix:nd 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.
