Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484796, here are decompositions:

19 + 31484777 = 31484796
43 + 31484753 = 31484796
97 + 31484699 = 31484796
149 + 31484647 = 31484796
179 + 31484617 = 31484796
227 + 31484569 = 31484796
263 + 31484533 = 31484796
283 + 31484513 = 31484796

Showing the first eight; more decompositions exist.
