Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488358, here are decompositions:

79 + 2147488279 = 2147488358
109 + 2147488249 = 2147488358
331 + 2147488027 = 2147488358
349 + 2147488009 = 2147488358
487 + 2147487871 = 2147488358
541 + 2147487817 = 2147488358
577 + 2147487781 = 2147488358
601 + 2147487757 = 2147488358

Showing the first eight; more decompositions exist.

IPv4 address
