Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459308, here are decompositions:

17 + 31459291 = 31459308
19 + 31459289 = 31459308
47 + 31459261 = 31459308
107 + 31459201 = 31459308
109 + 31459199 = 31459308
157 + 31459151 = 31459308
197 + 31459111 = 31459308
239 + 31459069 = 31459308

Showing the first eight; more decompositions exist.
