Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527716, here are decompositions:

  • 7 + 31527709 = 31527716
  • 13 + 31527703 = 31527716
  • 19 + 31527697 = 31527716
  • 139 + 31527577 = 31527716
  • 193 + 31527523 = 31527716
  • 373 + 31527343 = 31527716
  • 439 + 31527277 = 31527716
  • 463 + 31527253 = 31527716

Showing the first eight; more decompositions exist.
