Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26436, here are decompositions:

  • 5 + 26431 = 26436
  • 13 + 26423 = 26436
  • 19 + 26417 = 26436
  • 29 + 26407 = 26436
  • 37 + 26399 = 26436
  • 43 + 26393 = 26436
  • 79 + 26357 = 26436
  • 89 + 26347 = 26436

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26436 first appears in π at position 236,820 of the decimal expansion (the 236,820ordinal-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.
