Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525992, here are decompositions:

  • 11 + 31525981 = 31525992
  • 41 + 31525951 = 31525992
  • 73 + 31525919 = 31525992
  • 79 + 31525913 = 31525992
  • 83 + 31525909 = 31525992
  • 89 + 31525903 = 31525992
  • 101 + 31525891 = 31525992
  • 103 + 31525889 = 31525992

Showing the first eight; more decompositions exist.
