Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459422, here are decompositions:

13 + 31459409 = 31459422
23 + 31459399 = 31459422
73 + 31459349 = 31459422
79 + 31459343 = 31459422
83 + 31459339 = 31459422
101 + 31459321 = 31459422
131 + 31459291 = 31459422
199 + 31459223 = 31459422

Showing the first eight; more decompositions exist.
