Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26100, here are decompositions:

  • 17 + 26083 = 26100
  • 47 + 26053 = 26100
  • 59 + 26041 = 26100
  • 71 + 26029 = 26100
  • 79 + 26021 = 26100
  • 83 + 26017 = 26100
  • 97 + 26003 = 26100
  • 101 + 25999 = 26100

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26100 first appears in π at position 63,510 of the decimal expansion (the 63,510ordinal-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.
