Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527726, here are decompositions:

  • 17 + 31527709 = 31527726
  • 23 + 31527703 = 31527726
  • 29 + 31527697 = 31527726
  • 37 + 31527689 = 31527726
  • 67 + 31527659 = 31527726
  • 149 + 31527577 = 31527726
  • 157 + 31527569 = 31527726
  • 193 + 31527533 = 31527726

Showing the first eight; more decompositions exist.
