Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40570, here are decompositions:

  • 11 + 40559 = 40570
  • 41 + 40529 = 40570
  • 71 + 40499 = 40570
  • 83 + 40487 = 40570
  • 137 + 40433 = 40570
  • 227 + 40343 = 40570
  • 281 + 40289 = 40570
  • 293 + 40277 = 40570

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40570 first appears in π at position 131,249 of the decimal expansion (the 131,249ordinal-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.
