Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26404, here are decompositions:

  • 5 + 26399 = 26404
  • 11 + 26393 = 26404
  • 17 + 26387 = 26404
  • 47 + 26357 = 26404
  • 83 + 26321 = 26404
  • 107 + 26297 = 26404
  • 137 + 26267 = 26404
  • 167 + 26237 = 26404

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26404 first appears in π at position 72,026 of the decimal expansion (the 72,026ordinal-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.
