Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623610, here are decompositions:

3 + 31623607 = 31623610
89 + 31623521 = 31623610
101 + 31623509 = 31623610
113 + 31623497 = 31623610
131 + 31623479 = 31623610
149 + 31623461 = 31623610
167 + 31623443 = 31623610
233 + 31623377 = 31623610

Showing the first eight; more decompositions exist.
