Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525802, here are decompositions:

  • 3 + 31525799 = 31525802
  • 19 + 31525783 = 31525802
  • 31 + 31525771 = 31525802
  • 79 + 31525723 = 31525802
  • 103 + 31525699 = 31525802
  • 151 + 31525651 = 31525802
  • 193 + 31525609 = 31525802
  • 199 + 31525603 = 31525802

Showing the first eight; more decompositions exist.
