Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606594, here are decompositions:

11 + 31606583 = 31606594
53 + 31606541 = 31606594
101 + 31606493 = 31606594
197 + 31606397 = 31606594
251 + 31606343 = 31606594
263 + 31606331 = 31606594
281 + 31606313 = 31606594
311 + 31606283 = 31606594

Showing the first eight; more decompositions exist.
