Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590474, here are decompositions:

5 + 31590469 = 31590474
7 + 31590467 = 31590474
11 + 31590463 = 31590474
23 + 31590451 = 31590474
31 + 31590443 = 31590474
53 + 31590421 = 31590474
61 + 31590413 = 31590474
73 + 31590401 = 31590474

Showing the first eight; more decompositions exist.
