Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467854, here are decompositions:

  • 41 + 2147467813 = 2147467854
  • 53 + 2147467801 = 2147467854
  • 61 + 2147467793 = 2147467854
  • 107 + 2147467747 = 2147467854
  • 137 + 2147467717 = 2147467854
  • 157 + 2147467697 = 2147467854
  • 223 + 2147467631 = 2147467854
  • 227 + 2147467627 = 2147467854

Showing the first eight; more decompositions exist.
