Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1974, here are decompositions:

  • 23 + 1951 = 1974
  • 41 + 1933 = 1974
  • 43 + 1931 = 1974
  • 61 + 1913 = 1974
  • 67 + 1907 = 1974
  • 73 + 1901 = 1974
  • 97 + 1877 = 1974
  • 101 + 1873 = 1974

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1974 first appears in π at position 8,650 of the decimal expansion (the 8,650ordinal-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.
