Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527638, here are decompositions:

  • 61 + 31527577 = 31527638
  • 97 + 31527541 = 31527638
  • 139 + 31527499 = 31527638
  • 157 + 31527481 = 31527638
  • 487 + 31527151 = 31527638
  • 739 + 31526899 = 31527638
  • 757 + 31526881 = 31527638
  • 829 + 31526809 = 31527638

Showing the first eight; more decompositions exist.
