Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623684, here are decompositions:

13 + 31623671 = 31623684
17 + 31623667 = 31623684
61 + 31623623 = 31623684
67 + 31623617 = 31623684
163 + 31623521 = 31623684
173 + 31623511 = 31623684
193 + 31623491 = 31623684
223 + 31623461 = 31623684

Showing the first eight; more decompositions exist.
