Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580362, here are decompositions:

41 + 31580321 = 31580362
83 + 31580279 = 31580362
89 + 31580273 = 31580362
131 + 31580231 = 31580362
179 + 31580183 = 31580362
251 + 31580111 = 31580362
269 + 31580093 = 31580362
311 + 31580051 = 31580362

Showing the first eight; more decompositions exist.
