Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26828, here are decompositions:

  • 7 + 26821 = 26828
  • 97 + 26731 = 26828
  • 127 + 26701 = 26828
  • 181 + 26647 = 26828
  • 271 + 26557 = 26828
  • 331 + 26497 = 26828
  • 349 + 26479 = 26828
  • 379 + 26449 = 26828

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26828 first appears in π at position 69,475 of the decimal expansion (the 69,475ordinal-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.
