Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526802, here are decompositions:

  • 11 + 31526791 = 31526802
  • 29 + 31526773 = 31526802
  • 31 + 31526771 = 31526802
  • 53 + 31526749 = 31526802
  • 71 + 31526731 = 31526802
  • 79 + 31526723 = 31526802
  • 89 + 31526713 = 31526802
  • 113 + 31526689 = 31526802

Showing the first eight; more decompositions exist.
