Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607342, here are decompositions:

  • 43 + 31607299 = 31607342
  • 61 + 31607281 = 31607342
  • 79 + 31607263 = 31607342
  • 241 + 31607101 = 31607342
  • 379 + 31606963 = 31607342
  • 439 + 31606903 = 31607342
  • 463 + 31606879 = 31607342
  • 601 + 31606741 = 31607342

Showing the first eight; more decompositions exist.
