Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481158, here are decompositions:

  • 7 + 2147481151 = 2147481158
  • 19 + 2147481139 = 2147481158
  • 127 + 2147481031 = 2147481158
  • 139 + 2147481019 = 2147481158
  • 367 + 2147480791 = 2147481158
  • 547 + 2147480611 = 2147481158
  • 607 + 2147480551 = 2147481158
  • 631 + 2147480527 = 2147481158

Showing the first eight; more decompositions exist.
