Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525984, here are decompositions:

  • 3 + 31525981 = 31525984
  • 71 + 31525913 = 31525984
  • 167 + 31525817 = 31525984
  • 173 + 31525811 = 31525984
  • 197 + 31525787 = 31525984
  • 383 + 31525601 = 31525984
  • 431 + 31525553 = 31525984
  • 563 + 31525421 = 31525984

Showing the first eight; more decompositions exist.
