Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532162, here are decompositions:

  • 73 + 31532089 = 31532162
  • 241 + 31531921 = 31532162
  • 349 + 31531813 = 31532162
  • 523 + 31531639 = 31532162
  • 691 + 31531471 = 31532162
  • 709 + 31531453 = 31532162
  • 859 + 31531303 = 31532162
  • 1063 + 31531099 = 31532162

Showing the first eight; more decompositions exist.
