Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23426, here are decompositions:

  • 157 + 23269 = 23426
  • 199 + 23227 = 23426
  • 223 + 23203 = 23426
  • 229 + 23197 = 23426
  • 283 + 23143 = 23426
  • 367 + 23059 = 23426
  • 373 + 23053 = 23426
  • 397 + 23029 = 23426

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23426 first appears in π at position 144,525 of the decimal expansion (the 144,525ordinal-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.
