Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525342, here are decompositions:

  • 11 + 31525331 = 31525342
  • 53 + 31525289 = 31525342
  • 59 + 31525283 = 31525342
  • 113 + 31525229 = 31525342
  • 131 + 31525211 = 31525342
  • 179 + 31525163 = 31525342
  • 239 + 31525103 = 31525342
  • 311 + 31525031 = 31525342

Showing the first eight; more decompositions exist.
