Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553110, here are decompositions:

  • 41 + 31553069 = 31553110
  • 47 + 31553063 = 31553110
  • 89 + 31553021 = 31553110
  • 167 + 31552943 = 31553110
  • 191 + 31552919 = 31553110
  • 227 + 31552883 = 31553110
  • 257 + 31552853 = 31553110
  • 263 + 31552847 = 31553110

Showing the first eight; more decompositions exist.
