Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473740, here are decompositions:

  • 7 + 31473733 = 31473740
  • 37 + 31473703 = 31473740
  • 157 + 31473583 = 31473740
  • 211 + 31473529 = 31473740
  • 283 + 31473457 = 31473740
  • 409 + 31473331 = 31473740
  • 457 + 31473283 = 31473740
  • 499 + 31473241 = 31473740

Showing the first eight; more decompositions exist.
