Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606456, here are decompositions:

59 + 31606397 = 31606456
83 + 31606373 = 31606456
113 + 31606343 = 31606456
137 + 31606319 = 31606456
173 + 31606283 = 31606456
179 + 31606277 = 31606456
269 + 31606187 = 31606456
359 + 31606097 = 31606456

Showing the first eight; more decompositions exist.
