Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459064, here are decompositions:

97 + 31458967 = 31459064
127 + 31458937 = 31459064
151 + 31458913 = 31459064
157 + 31458907 = 31459064
163 + 31458901 = 31459064
277 + 31458787 = 31459064
367 + 31458697 = 31459064
397 + 31458667 = 31459064

Showing the first eight; more decompositions exist.
