Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623704, here are decompositions:

3 + 31623701 = 31623704
37 + 31623667 = 31623704
97 + 31623607 = 31623704
181 + 31623523 = 31623704
193 + 31623511 = 31623704
223 + 31623481 = 31623704
283 + 31623421 = 31623704
331 + 31623373 = 31623704

Showing the first eight; more decompositions exist.
