Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459078, here are decompositions:

5 + 31459073 = 31459078
47 + 31459031 = 31459078
59 + 31459019 = 31459078
257 + 31458821 = 31459078
281 + 31458797 = 31459078
317 + 31458761 = 31459078
359 + 31458719 = 31459078
389 + 31458689 = 31459078

Showing the first eight; more decompositions exist.
