Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527710, here are decompositions:

  • 7 + 31527703 = 31527710
  • 13 + 31527697 = 31527710
  • 127 + 31527583 = 31527710
  • 211 + 31527499 = 31527710
  • 229 + 31527481 = 31527710
  • 367 + 31527343 = 31527710
  • 433 + 31527277 = 31527710
  • 457 + 31527253 = 31527710

Showing the first eight; more decompositions exist.
