Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459252, here are decompositions:

29 + 31459223 = 31459252
53 + 31459199 = 31459252
101 + 31459151 = 31459252
179 + 31459073 = 31459252
233 + 31459019 = 31459252
269 + 31458983 = 31459252
389 + 31458863 = 31459252
431 + 31458821 = 31459252

Showing the first eight; more decompositions exist.
