Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590366, here are decompositions:

13 + 31590353 = 31590366
23 + 31590343 = 31590366
53 + 31590313 = 31590366
89 + 31590277 = 31590366
97 + 31590269 = 31590366
103 + 31590263 = 31590366
179 + 31590187 = 31590366
229 + 31590137 = 31590366

Showing the first eight; more decompositions exist.
