Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486680, here are decompositions:

11 + 2147486669 = 2147486680
149 + 2147486531 = 2147486680
167 + 2147486513 = 2147486680
173 + 2147486507 = 2147486680
179 + 2147486501 = 2147486680
257 + 2147486423 = 2147486680
281 + 2147486399 = 2147486680
293 + 2147486387 = 2147486680

Showing the first eight; more decompositions exist.

IPv4 address
