Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554474, here are decompositions:

11 + 31554463 = 31554474
41 + 31554433 = 31554474
73 + 31554401 = 31554474
113 + 31554361 = 31554474
137 + 31554337 = 31554474
191 + 31554283 = 31554474
233 + 31554241 = 31554474
293 + 31554181 = 31554474

Showing the first eight; more decompositions exist.
