Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509110, here are decompositions:

  • 19 + 31509091 = 31509110
  • 79 + 31509031 = 31509110
  • 151 + 31508959 = 31509110
  • 163 + 31508947 = 31509110
  • 223 + 31508887 = 31509110
  • 379 + 31508731 = 31509110
  • 397 + 31508713 = 31509110
  • 433 + 31508677 = 31509110

Showing the first eight; more decompositions exist.
