Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489788, here are decompositions:

71 + 2147489717 = 2147489788
89 + 2147489699 = 2147489788
137 + 2147489651 = 2147489788
149 + 2147489639 = 2147489788
251 + 2147489537 = 2147489788
347 + 2147489441 = 2147489788
491 + 2147489297 = 2147489788
701 + 2147489087 = 2147489788

Showing the first eight; more decompositions exist.

IPv4 address
