Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554336, here are decompositions:

53 + 31554283 = 31554336
137 + 31554199 = 31554336
157 + 31554179 = 31554336
173 + 31554163 = 31554336
193 + 31554143 = 31554336
263 + 31554073 = 31554336
293 + 31554043 = 31554336
349 + 31553987 = 31554336

Showing the first eight; more decompositions exist.
