Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147376666, here are decompositions:

  • 109 + 2147376557 = 2147376666
  • 137 + 2147376529 = 2147376666
  • 157 + 2147376509 = 2147376666
  • 163 + 2147376503 = 2147376666
  • 179 + 2147376487 = 2147376666
  • 233 + 2147376433 = 2147376666
  • 577 + 2147376089 = 2147376666
  • 593 + 2147376073 = 2147376666

Showing the first eight; more decompositions exist.
