Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623604, here are decompositions:

  • 83 + 31623521 = 31623604
  • 107 + 31623497 = 31623604
  • 113 + 31623491 = 31623604
  • 227 + 31623377 = 31623604
  • 347 + 31623257 = 31623604
  • 431 + 31623173 = 31623604
  • 491 + 31623113 = 31623604
  • 557 + 31623047 = 31623604

Showing the first eight; more decompositions exist.
