Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459636, here are decompositions:

3 + 31459633 = 31459636
17 + 31459619 = 31459636
83 + 31459553 = 31459636
137 + 31459499 = 31459636
149 + 31459487 = 31459636
179 + 31459457 = 31459636
227 + 31459409 = 31459636
293 + 31459343 = 31459636

Showing the first eight; more decompositions exist.
