Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498728, here are decompositions:

5 + 2147498723 = 2147498728
71 + 2147498657 = 2147498728
101 + 2147498627 = 2147498728
227 + 2147498501 = 2147498728
257 + 2147498471 = 2147498728
449 + 2147498279 = 2147498728
587 + 2147498141 = 2147498728
821 + 2147497907 = 2147498728

Showing the first eight; more decompositions exist.

IPv4 address
