Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459738, here are decompositions:

5 + 31459733 = 31459738
29 + 31459709 = 31459738
41 + 31459697 = 31459738
59 + 31459679 = 31459738
71 + 31459667 = 31459738
197 + 31459541 = 31459738
239 + 31459499 = 31459738
251 + 31459487 = 31459738

Showing the first eight; more decompositions exist.
