Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486686, here are decompositions:

17 + 2147486669 = 2147486686
173 + 2147486513 = 2147486686
179 + 2147486507 = 2147486686
227 + 2147486459 = 2147486686
263 + 2147486423 = 2147486686
347 + 2147486339 = 2147486686
557 + 2147486129 = 2147486686
677 + 2147486009 = 2147486686

Showing the first eight; more decompositions exist.

IPv4 address
