Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459854, here are decompositions:

5 + 31459849 = 31459854
7 + 31459847 = 31459854
47 + 31459807 = 31459854
131 + 31459723 = 31459854
137 + 31459717 = 31459854
157 + 31459697 = 31459854
193 + 31459661 = 31459854
233 + 31459621 = 31459854

Showing the first eight; more decompositions exist.
