Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147486564, here are decompositions:

7 + 2147486557 = 2147486564
37 + 2147486527 = 2147486564
151 + 2147486413 = 2147486564
271 + 2147486293 = 2147486564
367 + 2147486197 = 2147486564
541 + 2147486023 = 2147486564
547 + 2147486017 = 2147486564
757 + 2147485807 = 2147486564

Showing the first eight; more decompositions exist.

IPv4 address
