Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590584, here are decompositions:

13 + 31590571 = 31590584
97 + 31590487 = 31590584
163 + 31590421 = 31590584
241 + 31590343 = 31590584
271 + 31590313 = 31590584
307 + 31590277 = 31590584
373 + 31590211 = 31590584
397 + 31590187 = 31590584

Showing the first eight; more decompositions exist.
