Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459460, here are decompositions:

3 + 31459457 = 31459460
61 + 31459399 = 31459460
73 + 31459387 = 31459460
103 + 31459357 = 31459460
139 + 31459321 = 31459460
199 + 31459261 = 31459460
337 + 31459123 = 31459460
349 + 31459111 = 31459460

Showing the first eight; more decompositions exist.
