Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554522, here are decompositions:

5 + 31554517 = 31554522
11 + 31554511 = 31554522
29 + 31554493 = 31554522
59 + 31554463 = 31554522
73 + 31554449 = 31554522
89 + 31554433 = 31554522
113 + 31554409 = 31554522
239 + 31554283 = 31554522

Showing the first eight; more decompositions exist.
