Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554922, here are decompositions:

23 + 31554899 = 31554922
29 + 31554893 = 31554922
59 + 31554863 = 31554922
71 + 31554851 = 31554922
131 + 31554791 = 31554922
173 + 31554749 = 31554922
251 + 31554671 = 31554922
263 + 31554659 = 31554922

Showing the first eight; more decompositions exist.
