Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26128, here are decompositions:

  • 17 + 26111 = 26128
  • 29 + 26099 = 26128
  • 107 + 26021 = 26128
  • 131 + 25997 = 26128
  • 197 + 25931 = 26128
  • 239 + 25889 = 26128
  • 281 + 25847 = 26128
  • 449 + 25679 = 26128

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26128 first appears in π at position 164,138 of the decimal expansion (the 164,138ordinal-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.
