Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489290, here are decompositions:

47 + 2147489243 = 2147489290
83 + 2147489207 = 2147489290
293 + 2147488997 = 2147489290
383 + 2147488907 = 2147489290
431 + 2147488859 = 2147489290
563 + 2147488727 = 2147489290
599 + 2147488691 = 2147489290
647 + 2147488643 = 2147489290

Showing the first eight; more decompositions exist.

IPv4 address
