Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459122, here are decompositions:

11 + 31459111 = 31459122
29 + 31459093 = 31459122
53 + 31459069 = 31459122
59 + 31459063 = 31459122
103 + 31459019 = 31459122
139 + 31458983 = 31459122
199 + 31458923 = 31459122
293 + 31458829 = 31459122

Showing the first eight; more decompositions exist.
