Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26438, here are decompositions:

  • 7 + 26431 = 26438
  • 31 + 26407 = 26438
  • 67 + 26371 = 26438
  • 211 + 26227 = 26438
  • 229 + 26209 = 26438
  • 277 + 26161 = 26438
  • 331 + 26107 = 26438
  • 397 + 26041 = 26438

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26438 first appears in π at position 376,306 of the decimal expansion (the 376,306ordinal-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.
