Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500198, here are decompositions:

59 + 2147500139 = 2147500198
71 + 2147500127 = 2147500198
149 + 2147500049 = 2147500198
191 + 2147500007 = 2147500198
281 + 2147499917 = 2147500198
491 + 2147499707 = 2147500198
659 + 2147499539 = 2147500198
677 + 2147499521 = 2147500198

Showing the first eight; more decompositions exist.

IPv4 address
