Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498186, here are decompositions:

  • 7 + 2147498179 = 2147498186
  • 109 + 2147498077 = 2147498186
  • 487 + 2147497699 = 2147498186
  • 523 + 2147497663 = 2147498186
  • 727 + 2147497459 = 2147498186
  • 739 + 2147497447 = 2147498186
  • 1249 + 2147496937 = 2147498186
  • 1327 + 2147496859 = 2147498186

Showing the first eight; more decompositions exist.
