Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459576, here are decompositions:

23 + 31459553 = 31459576
59 + 31459517 = 31459576
89 + 31459487 = 31459576
167 + 31459409 = 31459576
227 + 31459349 = 31459576
233 + 31459343 = 31459576
353 + 31459223 = 31459576
359 + 31459217 = 31459576

Showing the first eight; more decompositions exist.
