Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459294, here are decompositions:

3 + 31459291 = 31459294
5 + 31459289 = 31459294
71 + 31459223 = 31459294
263 + 31459031 = 31459294
311 + 31458983 = 31459294
431 + 31458863 = 31459294
593 + 31458701 = 31459294
701 + 31458593 = 31459294

Showing the first eight; more decompositions exist.
