Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588550, here are decompositions:

67 + 31588483 = 31588550
79 + 31588471 = 31588550
109 + 31588441 = 31588550
151 + 31588399 = 31588550
181 + 31588369 = 31588550
193 + 31588357 = 31588550
199 + 31588351 = 31588550
229 + 31588321 = 31588550

Showing the first eight; more decompositions exist.
