Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554360, here are decompositions:

23 + 31554337 = 31554360
73 + 31554287 = 31554360
179 + 31554181 = 31554360
181 + 31554179 = 31554360
197 + 31554163 = 31554360
199 + 31554161 = 31554360
239 + 31554121 = 31554360
283 + 31554077 = 31554360

Showing the first eight; more decompositions exist.
