Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459732, here are decompositions:

23 + 31459709 = 31459732
53 + 31459679 = 31459732
71 + 31459661 = 31459732
113 + 31459619 = 31459732
179 + 31459553 = 31459732
191 + 31459541 = 31459732
233 + 31459499 = 31459732
383 + 31459349 = 31459732

Showing the first eight; more decompositions exist.
