Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459384, here are decompositions:

41 + 31459343 = 31459384
167 + 31459217 = 31459384
233 + 31459151 = 31459384
251 + 31459133 = 31459384
311 + 31459073 = 31459384
353 + 31459031 = 31459384
401 + 31458983 = 31459384
431 + 31458953 = 31459384

Showing the first eight; more decompositions exist.
