Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16426, here are decompositions:

  • 5 + 16421 = 16426
  • 107 + 16319 = 16426
  • 173 + 16253 = 16426
  • 197 + 16229 = 16426
  • 233 + 16193 = 16426
  • 239 + 16187 = 16426
  • 353 + 16073 = 16426
  • 359 + 16067 = 16426

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16426 first appears in π at position 98,934 of the decimal expansion (the 98,934ordinal-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.
