Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147428132, here are decompositions:

  • 23 + 2147428109 = 2147428132
  • 293 + 2147427839 = 2147428132
  • 431 + 2147427701 = 2147428132
  • 569 + 2147427563 = 2147428132
  • 659 + 2147427473 = 2147428132
  • 911 + 2147427221 = 2147428132
  • 1049 + 2147427083 = 2147428132
  • 1091 + 2147427041 = 2147428132

Showing the first eight; more decompositions exist.
