Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459352, here are decompositions:

3 + 31459349 = 31459352
13 + 31459339 = 31459352
31 + 31459321 = 31459352
61 + 31459291 = 31459352
151 + 31459201 = 31459352
229 + 31459123 = 31459352
241 + 31459111 = 31459352
283 + 31459069 = 31459352

Showing the first eight; more decompositions exist.
