Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473182, here are decompositions:

  • 19 + 31473163 = 31473182
  • 31 + 31473151 = 31473182
  • 73 + 31473109 = 31473182
  • 151 + 31473031 = 31473182
  • 199 + 31472983 = 31473182
  • 331 + 31472851 = 31473182
  • 409 + 31472773 = 31473182
  • 571 + 31472611 = 31473182

Showing the first eight; more decompositions exist.
