Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22154, here are decompositions:

  • 7 + 22147 = 22154
  • 31 + 22123 = 22154
  • 43 + 22111 = 22154
  • 61 + 22093 = 22154
  • 103 + 22051 = 22154
  • 127 + 22027 = 22154
  • 151 + 22003 = 22154
  • 157 + 21997 = 22154

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 22154 first appears in π at position 26,814 of the decimal expansion (the 26,814ordinal-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.
