Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147376630, here are decompositions:

  • 13 + 2147376617 = 2147376630
  • 73 + 2147376557 = 2147376630
  • 79 + 2147376551 = 2147376630
  • 83 + 2147376547 = 2147376630
  • 101 + 2147376529 = 2147376630
  • 127 + 2147376503 = 2147376630
  • 167 + 2147376463 = 2147376630
  • 173 + 2147376457 = 2147376630

Showing the first eight; more decompositions exist.
