Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459348, here are decompositions:

5 + 31459343 = 31459348
59 + 31459289 = 31459348
131 + 31459217 = 31459348
149 + 31459199 = 31459348
197 + 31459151 = 31459348
317 + 31459031 = 31459348
587 + 31458761 = 31459348
647 + 31458701 = 31459348

Showing the first eight; more decompositions exist.
