Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606260, here are decompositions:

73 + 31606187 = 31606260
79 + 31606181 = 31606260
163 + 31606097 = 31606260
173 + 31606087 = 31606260
181 + 31606079 = 31606260
193 + 31606067 = 31606260
199 + 31606061 = 31606260
211 + 31606049 = 31606260

Showing the first eight; more decompositions exist.
