Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623598, here are decompositions:

89 + 31623509 = 31623598
101 + 31623497 = 31623598
107 + 31623491 = 31623598
137 + 31623461 = 31623598
389 + 31623209 = 31623598
431 + 31623167 = 31623598
557 + 31623041 = 31623598
647 + 31622951 = 31623598

Showing the first eight; more decompositions exist.
