Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590566, here are decompositions:

67 + 31590499 = 31590566
79 + 31590487 = 31590566
97 + 31590469 = 31590566
103 + 31590463 = 31590566
223 + 31590343 = 31590566
379 + 31590187 = 31590566
433 + 31590133 = 31590566
613 + 31589953 = 31590566

Showing the first eight; more decompositions exist.
