Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147430028, here are decompositions:

  • 17 + 2147430011 = 2147430028
  • 59 + 2147429969 = 2147430028
  • 131 + 2147429897 = 2147430028
  • 179 + 2147429849 = 2147430028
  • 467 + 2147429561 = 2147430028
  • 587 + 2147429441 = 2147430028
  • 677 + 2147429351 = 2147430028
  • 719 + 2147429309 = 2147430028

Showing the first eight; more decompositions exist.
