Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606362, here are decompositions:

19 + 31606343 = 31606362
23 + 31606339 = 31606362
31 + 31606331 = 31606362
43 + 31606319 = 31606362
79 + 31606283 = 31606362
83 + 31606279 = 31606362
101 + 31606261 = 31606362
181 + 31606181 = 31606362

Showing the first eight; more decompositions exist.
