Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590494, here are decompositions:

7 + 31590487 = 31590494
31 + 31590463 = 31590494
43 + 31590451 = 31590494
73 + 31590421 = 31590494
97 + 31590397 = 31590494
151 + 31590343 = 31590494
181 + 31590313 = 31590494
283 + 31590211 = 31590494

Showing the first eight; more decompositions exist.
