Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573264, here are decompositions:

  • 3 + 31573261 = 31573264
  • 5 + 31573259 = 31573264
  • 11 + 31573253 = 31573264
  • 53 + 31573211 = 31573264
  • 101 + 31573163 = 31573264
  • 113 + 31573151 = 31573264
  • 131 + 31573133 = 31573264
  • 137 + 31573127 = 31573264

Showing the first eight; more decompositions exist.
