Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492740, here are decompositions:

101 + 2147492639 = 2147492740
131 + 2147492609 = 2147492740
149 + 2147492591 = 2147492740
251 + 2147492489 = 2147492740
293 + 2147492447 = 2147492740
311 + 2147492429 = 2147492740
347 + 2147492393 = 2147492740
353 + 2147492387 = 2147492740

Showing the first eight; more decompositions exist.

IPv4 address
