Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597264, here are decompositions:

  • 3 + 31597261 = 31597264
  • 11 + 31597253 = 31597264
  • 113 + 31597151 = 31597264
  • 137 + 31597127 = 31597264
  • 233 + 31597031 = 31597264
  • 383 + 31596881 = 31597264
  • 443 + 31596821 = 31597264
  • 467 + 31596797 = 31597264

Showing the first eight; more decompositions exist.
