Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493574, here are decompositions:

263 + 2147493311 = 2147493574
293 + 2147493281 = 2147493574
521 + 2147493053 = 2147493574
557 + 2147493017 = 2147493574
953 + 2147492621 = 2147493574
977 + 2147492597 = 2147493574
983 + 2147492591 = 2147493574
1181 + 2147492393 = 2147493574

Showing the first eight; more decompositions exist.

IPv4 address
