Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2894, here are decompositions:

  • 7 + 2887 = 2894
  • 37 + 2857 = 2894
  • 43 + 2851 = 2894
  • 61 + 2833 = 2894
  • 97 + 2797 = 2894
  • 103 + 2791 = 2894
  • 127 + 2767 = 2894
  • 163 + 2731 = 2894

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 2894 first appears in π at position 13,059 of the decimal expansion (the 13,059ordinal-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.
