Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479636, here are decompositions:

  • 17 + 31479619 = 31479636
  • 43 + 31479593 = 31479636
  • 47 + 31479589 = 31479636
  • 59 + 31479577 = 31479636
  • 79 + 31479557 = 31479636
  • 137 + 31479499 = 31479636
  • 179 + 31479457 = 31479636
  • 197 + 31479439 = 31479636

Showing the first eight; more decompositions exist.
