Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40814, here are decompositions:

  • 13 + 40801 = 40814
  • 43 + 40771 = 40814
  • 223 + 40591 = 40814
  • 271 + 40543 = 40814
  • 283 + 40531 = 40814
  • 307 + 40507 = 40814
  • 331 + 40483 = 40814
  • 457 + 40357 = 40814

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40814 first appears in π at position 20,266 of the decimal expansion (the 20,266ordinal-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.
