Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459132, here are decompositions:

59 + 31459073 = 31459132
101 + 31459031 = 31459132
113 + 31459019 = 31459132
149 + 31458983 = 31459132
179 + 31458953 = 31459132
269 + 31458863 = 31459132
311 + 31458821 = 31459132
431 + 31458701 = 31459132

Showing the first eight; more decompositions exist.
