Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532386, here are decompositions:

  • 47 + 31532339 = 31532386
  • 107 + 31532279 = 31532386
  • 167 + 31532219 = 31532386
  • 269 + 31532117 = 31532386
  • 383 + 31532003 = 31532386
  • 419 + 31531967 = 31532386
  • 503 + 31531883 = 31532386
  • 569 + 31531817 = 31532386

Showing the first eight; more decompositions exist.
