Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590492, here are decompositions:

5 + 31590487 = 31590492
13 + 31590479 = 31590492
23 + 31590469 = 31590492
29 + 31590463 = 31590492
41 + 31590451 = 31590492
71 + 31590421 = 31590492
79 + 31590413 = 31590492
139 + 31590353 = 31590492

Showing the first eight; more decompositions exist.
