Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525050, here are decompositions:

  • 13 + 31525037 = 31525050
  • 19 + 31525031 = 31525050
  • 23 + 31525027 = 31525050
  • 43 + 31525007 = 31525050
  • 59 + 31524991 = 31525050
  • 61 + 31524989 = 31525050
  • 83 + 31524967 = 31525050
  • 113 + 31524937 = 31525050

Showing the first eight; more decompositions exist.
