Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147476790, here are decompositions:

13 + 2147476777 = 2147476790
97 + 2147476693 = 2147476790
103 + 2147476687 = 2147476790
127 + 2147476663 = 2147476790
271 + 2147476519 = 2147476790
373 + 2147476417 = 2147476790
409 + 2147476381 = 2147476790
463 + 2147476327 = 2147476790

Showing the first eight; more decompositions exist.

IPv4 address
