Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554548, here are decompositions:

7 + 31554541 = 31554548
31 + 31554517 = 31554548
37 + 31554511 = 31554548
139 + 31554409 = 31554548
211 + 31554337 = 31554548
307 + 31554241 = 31554548
349 + 31554199 = 31554548
367 + 31554181 = 31554548

Showing the first eight; more decompositions exist.
