Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554468, here are decompositions:

5 + 31554463 = 31554468
19 + 31554449 = 31554468
59 + 31554409 = 31554468
67 + 31554401 = 31554468
107 + 31554361 = 31554468
131 + 31554337 = 31554468
181 + 31554287 = 31554468
227 + 31554241 = 31554468

Showing the first eight; more decompositions exist.
