Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459354, here are decompositions:

5 + 31459349 = 31459354
11 + 31459343 = 31459354
131 + 31459223 = 31459354
137 + 31459217 = 31459354
281 + 31459073 = 31459354
401 + 31458953 = 31459354
431 + 31458923 = 31459354
491 + 31458863 = 31459354

Showing the first eight; more decompositions exist.
