Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590548, here are decompositions:

61 + 31590487 = 31590548
79 + 31590469 = 31590548
97 + 31590451 = 31590548
127 + 31590421 = 31590548
151 + 31590397 = 31590548
271 + 31590277 = 31590548
307 + 31590241 = 31590548
337 + 31590211 = 31590548

Showing the first eight; more decompositions exist.
