Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590498, here are decompositions:

11 + 31590487 = 31590498
19 + 31590479 = 31590498
29 + 31590469 = 31590498
31 + 31590467 = 31590498
47 + 31590451 = 31590498
97 + 31590401 = 31590498
101 + 31590397 = 31590498
127 + 31590371 = 31590498

Showing the first eight; more decompositions exist.
