Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590646, here are decompositions:

29 + 31590617 = 31590646
53 + 31590593 = 31590646
89 + 31590557 = 31590646
167 + 31590479 = 31590646
179 + 31590467 = 31590646
233 + 31590413 = 31590646
293 + 31590353 = 31590646
383 + 31590263 = 31590646

Showing the first eight; more decompositions exist.
