Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483628, here are decompositions:

31 + 31483597 = 31483628
79 + 31483549 = 31483628
157 + 31483471 = 31483628
181 + 31483447 = 31483628
199 + 31483429 = 31483628
277 + 31483351 = 31483628
367 + 31483261 = 31483628
541 + 31483087 = 31483628

Showing the first eight; more decompositions exist.
