Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40654, here are decompositions:

  • 17 + 40637 = 40654
  • 71 + 40583 = 40654
  • 167 + 40487 = 40654
  • 227 + 40427 = 40654
  • 293 + 40361 = 40654
  • 311 + 40343 = 40654
  • 401 + 40253 = 40654
  • 461 + 40193 = 40654

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40654 first appears in π at position 210,277 of the decimal expansion (the 210,277ordinal-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.
