Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525264, here are decompositions:

  • 3 + 31525261 = 31525264
  • 53 + 31525211 = 31525264
  • 101 + 31525163 = 31525264
  • 137 + 31525127 = 31525264
  • 227 + 31525037 = 31525264
  • 233 + 31525031 = 31525264
  • 257 + 31525007 = 31525264
  • 401 + 31524863 = 31525264

Showing the first eight; more decompositions exist.
