Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548406, here are decompositions:

  • 5 + 31548401 = 31548406
  • 83 + 31548323 = 31548406
  • 107 + 31548299 = 31548406
  • 137 + 31548269 = 31548406
  • 257 + 31548149 = 31548406
  • 359 + 31548047 = 31548406
  • 389 + 31548017 = 31548406
  • 557 + 31547849 = 31548406

Showing the first eight; more decompositions exist.
