Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525074, here are decompositions:

  • 37 + 31525037 = 31525074
  • 43 + 31525031 = 31525074
  • 47 + 31525027 = 31525074
  • 67 + 31525007 = 31525074
  • 83 + 31524991 = 31525074
  • 107 + 31524967 = 31525074
  • 137 + 31524937 = 31525074
  • 181 + 31524893 = 31525074

Showing the first eight; more decompositions exist.
