Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625588, here are decompositions:

  • 79 + 31625509 = 31625588
  • 157 + 31625431 = 31625588
  • 307 + 31625281 = 31625588
  • 409 + 31625179 = 31625588
  • 439 + 31625149 = 31625588
  • 457 + 31625131 = 31625588
  • 661 + 31624927 = 31625588
  • 727 + 31624861 = 31625588

Showing the first eight; more decompositions exist.
