Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40660, here are decompositions:

  • 23 + 40637 = 40660
  • 83 + 40577 = 40660
  • 101 + 40559 = 40660
  • 131 + 40529 = 40660
  • 167 + 40493 = 40660
  • 173 + 40487 = 40660
  • 227 + 40433 = 40660
  • 233 + 40427 = 40660

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40660 first appears in π at position 337,236 of the decimal expansion (the 337,236ordinal-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.
