Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443790, here are decompositions:

3 + 2147443787 = 2147443790
31 + 2147443759 = 2147443790
43 + 2147443747 = 2147443790
61 + 2147443729 = 2147443790
157 + 2147443633 = 2147443790
211 + 2147443579 = 2147443790
223 + 2147443567 = 2147443790
229 + 2147443561 = 2147443790

Showing the first eight; more decompositions exist.

IPv4 address
