Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467974, here are decompositions:

  • 7 + 2147467967 = 2147467974
  • 11 + 2147467963 = 2147467974
  • 53 + 2147467921 = 2147467974
  • 103 + 2147467871 = 2147467974
  • 173 + 2147467801 = 2147467974
  • 181 + 2147467793 = 2147467974
  • 227 + 2147467747 = 2147467974
  • 241 + 2147467733 = 2147467974

Showing the first eight; more decompositions exist.
