Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2570, here are decompositions:

  • 13 + 2557 = 2570
  • 19 + 2551 = 2570
  • 31 + 2539 = 2570
  • 67 + 2503 = 2570
  • 97 + 2473 = 2570
  • 103 + 2467 = 2570
  • 181 + 2389 = 2570
  • 193 + 2377 = 2570

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2570 first appears in π at position 4,057 of the decimal expansion (the 4,057ordinal-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.
