Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525838, here are decompositions:

  • 61 + 31525777 = 31525838
  • 67 + 31525771 = 31525838
  • 139 + 31525699 = 31525838
  • 151 + 31525687 = 31525838
  • 181 + 31525657 = 31525838
  • 229 + 31525609 = 31525838
  • 271 + 31525567 = 31525838
  • 349 + 31525489 = 31525838

Showing the first eight; more decompositions exist.
