Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484440, here are decompositions:

7 + 2147484433 = 2147484440
103 + 2147484337 = 2147484440
109 + 2147484331 = 2147484440
163 + 2147484277 = 2147484440
181 + 2147484259 = 2147484440
331 + 2147484109 = 2147484440
379 + 2147484061 = 2147484440
397 + 2147484043 = 2147484440

Showing the first eight; more decompositions exist.
