Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590360, here are decompositions:

7 + 31590353 = 31590360
17 + 31590343 = 31590360
47 + 31590313 = 31590360
83 + 31590277 = 31590360
97 + 31590263 = 31590360
149 + 31590211 = 31590360
173 + 31590187 = 31590360
199 + 31590161 = 31590360

Showing the first eight; more decompositions exist.
