Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459550, here are decompositions:

151 + 31459399 = 31459550
163 + 31459387 = 31459550
193 + 31459357 = 31459550
211 + 31459339 = 31459550
229 + 31459321 = 31459550
349 + 31459201 = 31459550
439 + 31459111 = 31459550
457 + 31459093 = 31459550

Showing the first eight; more decompositions exist.
