Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525650, here are decompositions:

  • 41 + 31525609 = 31525650
  • 43 + 31525607 = 31525650
  • 47 + 31525603 = 31525650
  • 61 + 31525589 = 31525650
  • 83 + 31525567 = 31525650
  • 97 + 31525553 = 31525650
  • 113 + 31525537 = 31525650
  • 151 + 31525499 = 31525650

Showing the first eight; more decompositions exist.
