Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554552, here are decompositions:

11 + 31554541 = 31554552
13 + 31554539 = 31554552
41 + 31554511 = 31554552
59 + 31554493 = 31554552
79 + 31554473 = 31554552
89 + 31554463 = 31554552
103 + 31554449 = 31554552
151 + 31554401 = 31554552

Showing the first eight; more decompositions exist.
