Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606356, here are decompositions:

13 + 31606343 = 31606356
17 + 31606339 = 31606356
37 + 31606319 = 31606356
43 + 31606313 = 31606356
59 + 31606297 = 31606356
73 + 31606283 = 31606356
79 + 31606277 = 31606356
269 + 31606087 = 31606356

Showing the first eight; more decompositions exist.
