Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525998, here are decompositions:

  • 17 + 31525981 = 31525998
  • 41 + 31525957 = 31525998
  • 47 + 31525951 = 31525998
  • 71 + 31525927 = 31525998
  • 79 + 31525919 = 31525998
  • 89 + 31525909 = 31525998
  • 107 + 31525891 = 31525998
  • 109 + 31525889 = 31525998

Showing the first eight; more decompositions exist.
