Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1894, here are decompositions:

  • 5 + 1889 = 1894
  • 17 + 1877 = 1894
  • 23 + 1871 = 1894
  • 47 + 1847 = 1894
  • 71 + 1823 = 1894
  • 83 + 1811 = 1894
  • 107 + 1787 = 1894
  • 173 + 1721 = 1894

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1894 first appears in π at position 12,964 of the decimal expansion (the 12,964ordinal-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.
