Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552090, here are decompositions:

  • 41 + 31552049 = 31552090
  • 71 + 31552019 = 31552090
  • 113 + 31551977 = 31552090
  • 131 + 31551959 = 31552090
  • 149 + 31551941 = 31552090
  • 233 + 31551857 = 31552090
  • 263 + 31551827 = 31552090
  • 419 + 31551671 = 31552090

Showing the first eight; more decompositions exist.
