Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588548, here are decompositions:

107 + 31588441 = 31588548
109 + 31588439 = 31588548
149 + 31588399 = 31588548
179 + 31588369 = 31588548
181 + 31588367 = 31588548
191 + 31588357 = 31588548
197 + 31588351 = 31588548
227 + 31588321 = 31588548

Showing the first eight; more decompositions exist.
