Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459476, here are decompositions:

19 + 31459457 = 31459476
43 + 31459433 = 31459476
67 + 31459409 = 31459476
89 + 31459387 = 31459476
127 + 31459349 = 31459476
137 + 31459339 = 31459476
277 + 31459199 = 31459476
353 + 31459123 = 31459476

Showing the first eight; more decompositions exist.
