Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525056, here are decompositions:

  • 19 + 31525037 = 31525056
  • 29 + 31525027 = 31525056
  • 67 + 31524989 = 31525056
  • 89 + 31524967 = 31525056
  • 163 + 31524893 = 31525056
  • 193 + 31524863 = 31525056
  • 263 + 31524793 = 31525056
  • 293 + 31524763 = 31525056

Showing the first eight; more decompositions exist.
