Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429998, here are decompositions:

  • 5 + 2147429993 = 2147429998
  • 29 + 2147429969 = 2147429998
  • 101 + 2147429897 = 2147429998
  • 149 + 2147429849 = 2147429998
  • 191 + 2147429807 = 2147429998
  • 557 + 2147429441 = 2147429998
  • 647 + 2147429351 = 2147429998
  • 761 + 2147429237 = 2147429998

Showing the first eight; more decompositions exist.
