Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554324, here are decompositions:

37 + 31554287 = 31554324
41 + 31554283 = 31554324
83 + 31554241 = 31554324
163 + 31554161 = 31554324
181 + 31554143 = 31554324
251 + 31554073 = 31554324
281 + 31554043 = 31554324
311 + 31554013 = 31554324

Showing the first eight; more decompositions exist.
