Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459412, here are decompositions:

3 + 31459409 = 31459412
13 + 31459399 = 31459412
73 + 31459339 = 31459412
151 + 31459261 = 31459412
211 + 31459201 = 31459412
349 + 31459063 = 31459412
499 + 31458913 = 31459412
613 + 31458799 = 31459412

Showing the first eight; more decompositions exist.
