Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489734, here are decompositions:

17 + 2147489717 = 2147489734
83 + 2147489651 = 2147489734
191 + 2147489543 = 2147489734
197 + 2147489537 = 2147489734
251 + 2147489483 = 2147489734
293 + 2147489441 = 2147489734
311 + 2147489423 = 2147489734
443 + 2147489291 = 2147489734

Showing the first eight; more decompositions exist.

IPv4 address
