Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492242, here are decompositions:

3 + 2147492239 = 2147492242
11 + 2147492231 = 2147492242
59 + 2147492183 = 2147492242
83 + 2147492159 = 2147492242
173 + 2147492069 = 2147492242
281 + 2147491961 = 2147492242
461 + 2147491781 = 2147492242
509 + 2147491733 = 2147492242

Showing the first eight; more decompositions exist.

IPv4 address
