Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459164, here are decompositions:

13 + 31459151 = 31459164
31 + 31459133 = 31459164
41 + 31459123 = 31459164
53 + 31459111 = 31459164
71 + 31459093 = 31459164
101 + 31459063 = 31459164
181 + 31458983 = 31459164
197 + 31458967 = 31459164

Showing the first eight; more decompositions exist.
