Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489754, here are decompositions:

37 + 2147489717 = 2147489754
41 + 2147489713 = 2147489754
101 + 2147489653 = 2147489754
103 + 2147489651 = 2147489754
167 + 2147489587 = 2147489754
211 + 2147489543 = 2147489754
251 + 2147489503 = 2147489754
271 + 2147489483 = 2147489754

Showing the first eight; more decompositions exist.

IPv4 address
