Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473118, here are decompositions:

  • 331 + 2147472787 = 2147473118
  • 367 + 2147472751 = 2147473118
  • 421 + 2147472697 = 2147473118
  • 619 + 2147472499 = 2147473118
  • 829 + 2147472289 = 2147473118
  • 859 + 2147472259 = 2147473118
  • 919 + 2147472199 = 2147473118
  • 1009 + 2147472109 = 2147473118

Showing the first eight; more decompositions exist.
