Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623204, here are decompositions:

5 + 31623199 = 31623204
23 + 31623181 = 31623204
31 + 31623173 = 31623204
37 + 31623167 = 31623204
83 + 31623121 = 31623204
157 + 31623047 = 31623204
163 + 31623041 = 31623204
181 + 31623023 = 31623204

Showing the first eight; more decompositions exist.
