Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459336, here are decompositions:

47 + 31459289 = 31459336
113 + 31459223 = 31459336
137 + 31459199 = 31459336
263 + 31459073 = 31459336
317 + 31459019 = 31459336
353 + 31458983 = 31459336
383 + 31458953 = 31459336
617 + 31458719 = 31459336

Showing the first eight; more decompositions exist.
