Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621362, here are decompositions:

  • 5 + 31621357 = 31621362
  • 43 + 31621319 = 31621362
  • 103 + 31621259 = 31621362
  • 193 + 31621169 = 31621362
  • 211 + 31621151 = 31621362
  • 229 + 31621133 = 31621362
  • 239 + 31621123 = 31621362
  • 281 + 31621081 = 31621362

Showing the first eight; more decompositions exist.
