Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585276, here are decompositions:

5 + 31585271 = 31585276
59 + 31585217 = 31585276
83 + 31585193 = 31585276
137 + 31585139 = 31585276
197 + 31585079 = 31585276
257 + 31585019 = 31585276
389 + 31584887 = 31585276
467 + 31584809 = 31585276

Showing the first eight; more decompositions exist.
