Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487398, here are decompositions:

97 + 2147487301 = 2147487398
139 + 2147487259 = 2147487398
151 + 2147487247 = 2147487398
211 + 2147487187 = 2147487398
229 + 2147487169 = 2147487398
241 + 2147487157 = 2147487398
349 + 2147487049 = 2147487398
541 + 2147486857 = 2147487398

Showing the first eight; more decompositions exist.

IPv4 address
