Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623696, here are decompositions:

29 + 31623667 = 31623696
73 + 31623623 = 31623696
79 + 31623617 = 31623696
89 + 31623607 = 31623696
107 + 31623589 = 31623696
173 + 31623523 = 31623696
197 + 31623499 = 31623696
199 + 31623497 = 31623696

Showing the first eight; more decompositions exist.
