Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493164, here are decompositions:

127 + 2147493037 = 2147493164
163 + 2147493001 = 2147493164
241 + 2147492923 = 2147493164
463 + 2147492701 = 2147493164
613 + 2147492551 = 2147493164
631 + 2147492533 = 2147493164
643 + 2147492521 = 2147493164
673 + 2147492491 = 2147493164

Showing the first eight; more decompositions exist.

IPv4 address
