Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585444, here are decompositions:

3 + 31585441 = 31585444
83 + 31585361 = 31585444
101 + 31585343 = 31585444
113 + 31585331 = 31585444
131 + 31585313 = 31585444
173 + 31585271 = 31585444
227 + 31585217 = 31585444
251 + 31585193 = 31585444

Showing the first eight; more decompositions exist.
