Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511314, here are decompositions:

  • 53 + 31511261 = 31511314
  • 83 + 31511231 = 31511314
  • 101 + 31511213 = 31511314
  • 167 + 31511147 = 31511314
  • 173 + 31511141 = 31511314
  • 257 + 31511057 = 31511314
  • 311 + 31511003 = 31511314
  • 383 + 31510931 = 31511314

Showing the first eight; more decompositions exist.
