Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490382, here are decompositions:

  • 293 + 2147490089 = 2147490382
  • 509 + 2147489873 = 2147490382
  • 563 + 2147489819 = 2147490382
  • 683 + 2147489699 = 2147490382
  • 743 + 2147489639 = 2147490382
  • 839 + 2147489543 = 2147490382
  • 941 + 2147489441 = 2147490382
  • 1091 + 2147489291 = 2147490382

Showing the first eight; more decompositions exist.
