Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496444, here are decompositions:

3 + 31496441 = 31496444
73 + 31496371 = 31496444
127 + 31496317 = 31496444
151 + 31496293 = 31496444
181 + 31496263 = 31496444
223 + 31496221 = 31496444
271 + 31496173 = 31496444
283 + 31496161 = 31496444

Showing the first eight; more decompositions exist.
