Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40930, here are decompositions:

  • 3 + 40927 = 40930
  • 47 + 40883 = 40930
  • 83 + 40847 = 40930
  • 89 + 40841 = 40930
  • 101 + 40829 = 40930
  • 107 + 40823 = 40930
  • 167 + 40763 = 40930
  • 179 + 40751 = 40930

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 40930 first appears in π at position 422,311 of the decimal expansion (the 422,311ordinal-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.
