Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477790, here are decompositions:

53 + 2147477737 = 2147477790
89 + 2147477701 = 2147477790
103 + 2147477687 = 2147477790
109 + 2147477681 = 2147477790
163 + 2147477627 = 2147477790
191 + 2147477599 = 2147477790
257 + 2147477533 = 2147477790
277 + 2147477513 = 2147477790

Showing the first eight; more decompositions exist.

IPv4 address
