Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484628, here are decompositions:

11 + 31484617 = 31484628
59 + 31484569 = 31484628
167 + 31484461 = 31484628
179 + 31484449 = 31484628
211 + 31484417 = 31484628
251 + 31484377 = 31484628
269 + 31484359 = 31484628
311 + 31484317 = 31484628

Showing the first eight; more decompositions exist.
