Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623394, here are decompositions:

17 + 31623377 = 31623394
137 + 31623257 = 31623394
227 + 31623167 = 31623394
281 + 31623113 = 31623394
347 + 31623047 = 31623394
353 + 31623041 = 31623394
443 + 31622951 = 31623394
461 + 31622933 = 31623394

Showing the first eight; more decompositions exist.
