Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498156, here are decompositions:

  • 79 + 2147498077 = 2147498156
  • 439 + 2147497717 = 2147498156
  • 457 + 2147497699 = 2147498156
  • 709 + 2147497447 = 2147498156
  • 919 + 2147497237 = 2147498156
  • 1117 + 2147497039 = 2147498156
  • 1297 + 2147496859 = 2147498156
  • 1303 + 2147496853 = 2147498156

Showing the first eight; more decompositions exist.
