Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23380, here are decompositions:

  • 11 + 23369 = 23380
  • 23 + 23357 = 23380
  • 41 + 23339 = 23380
  • 47 + 23333 = 23380
  • 53 + 23327 = 23380
  • 59 + 23321 = 23380
  • 83 + 23297 = 23380
  • 89 + 23291 = 23380

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23380 first appears in π at position 10,416 of the decimal expansion (the 10,416ordinal-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.
