Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459366, here are decompositions:

17 + 31459349 = 31459366
23 + 31459343 = 31459366
149 + 31459217 = 31459366
167 + 31459199 = 31459366
233 + 31459133 = 31459366
293 + 31459073 = 31459366
347 + 31459019 = 31459366
383 + 31458983 = 31459366

Showing the first eight; more decompositions exist.
