Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606342, here are decompositions:

3 + 31606339 = 31606342
11 + 31606331 = 31606342
23 + 31606319 = 31606342
29 + 31606313 = 31606342
59 + 31606283 = 31606342
263 + 31606079 = 31606342
281 + 31606061 = 31606342
293 + 31606049 = 31606342

Showing the first eight; more decompositions exist.
