Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459338, here are decompositions:

17 + 31459321 = 31459338
47 + 31459291 = 31459338
137 + 31459201 = 31459338
139 + 31459199 = 31459338
227 + 31459111 = 31459338
269 + 31459069 = 31459338
307 + 31459031 = 31459338
401 + 31458937 = 31459338

Showing the first eight; more decompositions exist.
