Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611382, here are decompositions:

  • 3 + 31611379 = 31611382
  • 41 + 31611341 = 31611382
  • 53 + 31611329 = 31611382
  • 59 + 31611323 = 31611382
  • 71 + 31611311 = 31611382
  • 83 + 31611299 = 31611382
  • 269 + 31611113 = 31611382
  • 281 + 31611101 = 31611382

Showing the first eight; more decompositions exist.
