Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459074, here are decompositions:

5 + 31459069 = 31459074
11 + 31459063 = 31459074
43 + 31459031 = 31459074
107 + 31458967 = 31459074
137 + 31458937 = 31459074
151 + 31458923 = 31459074
167 + 31458907 = 31459074
173 + 31458901 = 31459074

Showing the first eight; more decompositions exist.
