Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459304, here are decompositions:

13 + 31459291 = 31459304
43 + 31459261 = 31459304
103 + 31459201 = 31459304
181 + 31459123 = 31459304
193 + 31459111 = 31459304
211 + 31459093 = 31459304
241 + 31459063 = 31459304
337 + 31458967 = 31459304

Showing the first eight; more decompositions exist.
