Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487222, here are decompositions:

19 + 2147487203 = 2147487222
53 + 2147487169 = 2147487222
109 + 2147487113 = 2147487222
163 + 2147487059 = 2147487222
173 + 2147487049 = 2147487222
193 + 2147487029 = 2147487222
241 + 2147486981 = 2147487222
313 + 2147486909 = 2147487222

Showing the first eight; more decompositions exist.

IPv4 address
