Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459956, here are decompositions:

7 + 31459949 = 31459956
19 + 31459937 = 31459956
97 + 31459859 = 31459956
103 + 31459853 = 31459956
107 + 31459849 = 31459956
109 + 31459847 = 31459956
127 + 31459829 = 31459956
149 + 31459807 = 31459956

Showing the first eight; more decompositions exist.
