Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473678, here are decompositions:

  • 79 + 31473599 = 31473678
  • 97 + 31473581 = 31473678
  • 149 + 31473529 = 31473678
  • 191 + 31473487 = 31473678
  • 199 + 31473479 = 31473678
  • 241 + 31473437 = 31473678
  • 281 + 31473397 = 31473678
  • 347 + 31473331 = 31473678

Showing the first eight; more decompositions exist.
