Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459432, here are decompositions:

23 + 31459409 = 31459432
83 + 31459349 = 31459432
89 + 31459343 = 31459432
233 + 31459199 = 31459432
281 + 31459151 = 31459432
359 + 31459073 = 31459432
401 + 31459031 = 31459432
449 + 31458983 = 31459432

Showing the first eight; more decompositions exist.
