Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486690, here are decompositions:

73 + 2147486617 = 2147486690
103 + 2147486587 = 2147486690
163 + 2147486527 = 2147486690
277 + 2147486413 = 2147486690
373 + 2147486317 = 2147486690
379 + 2147486311 = 2147486690
397 + 2147486293 = 2147486690
421 + 2147486269 = 2147486690

Showing the first eight; more decompositions exist.

IPv4 address
