Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525410, here are decompositions:

  • 13 + 31525397 = 31525410
  • 31 + 31525379 = 31525410
  • 43 + 31525367 = 31525410
  • 67 + 31525343 = 31525410
  • 79 + 31525331 = 31525410
  • 127 + 31525283 = 31525410
  • 131 + 31525279 = 31525410
  • 149 + 31525261 = 31525410

Showing the first eight; more decompositions exist.
