Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459512, here are decompositions:

13 + 31459499 = 31459512
79 + 31459433 = 31459512
103 + 31459409 = 31459512
113 + 31459399 = 31459512
163 + 31459349 = 31459512
173 + 31459339 = 31459512
191 + 31459321 = 31459512
223 + 31459289 = 31459512

Showing the first eight; more decompositions exist.
