Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623310, here are decompositions:

53 + 31623257 = 31623310
101 + 31623209 = 31623310
137 + 31623173 = 31623310
197 + 31623113 = 31623310
263 + 31623047 = 31623310
269 + 31623041 = 31623310
359 + 31622951 = 31623310
569 + 31622741 = 31623310

Showing the first eight; more decompositions exist.
