Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459582, here are decompositions:

29 + 31459553 = 31459582
41 + 31459541 = 31459582
83 + 31459499 = 31459582
149 + 31459433 = 31459582
173 + 31459409 = 31459582
233 + 31459349 = 31459582
239 + 31459343 = 31459582
293 + 31459289 = 31459582

Showing the first eight; more decompositions exist.
