Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503212, here are decompositions:

  • 3 + 31503209 = 31503212
  • 31 + 31503181 = 31503212
  • 61 + 31503151 = 31503212
  • 73 + 31503139 = 31503212
  • 109 + 31503103 = 31503212
  • 151 + 31503061 = 31503212
  • 271 + 31502941 = 31503212
  • 331 + 31502881 = 31503212

Showing the first eight; more decompositions exist.
