Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1924, here are decompositions:

  • 11 + 1913 = 1924
  • 17 + 1907 = 1924
  • 23 + 1901 = 1924
  • 47 + 1877 = 1924
  • 53 + 1871 = 1924
  • 101 + 1823 = 1924
  • 113 + 1811 = 1924
  • 137 + 1787 = 1924

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1924 first appears in π at position 28,963 of the decimal expansion (the 28,963ordinal-suffix:rd 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.
