Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147376560, here are decompositions:

  • 3 + 2147376557 = 2147376560
  • 13 + 2147376547 = 2147376560
  • 31 + 2147376529 = 2147376560
  • 73 + 2147376487 = 2147376560
  • 97 + 2147376463 = 2147376560
  • 103 + 2147376457 = 2147376560
  • 127 + 2147376433 = 2147376560
  • 181 + 2147376379 = 2147376560

Showing the first eight; more decompositions exist.
