Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459462, here are decompositions:

5 + 31459457 = 31459462
29 + 31459433 = 31459462
53 + 31459409 = 31459462
113 + 31459349 = 31459462
173 + 31459289 = 31459462
239 + 31459223 = 31459462
263 + 31459199 = 31459462
311 + 31459151 = 31459462

Showing the first eight; more decompositions exist.
