Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26558, here are decompositions:

  • 19 + 26539 = 26558
  • 61 + 26497 = 26558
  • 79 + 26479 = 26558
  • 109 + 26449 = 26558
  • 127 + 26431 = 26558
  • 151 + 26407 = 26558
  • 211 + 26347 = 26558
  • 241 + 26317 = 26558

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26558 first appears in π at position 13,273 of the decimal expansion (the 13,273ordinal-suffix:rd 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.
