Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623066, here are decompositions:

5 + 31623061 = 31623066
19 + 31623047 = 31623066
43 + 31623023 = 31623066
107 + 31622959 = 31623066
127 + 31622939 = 31623066
173 + 31622893 = 31623066
229 + 31622837 = 31623066
257 + 31622809 = 31623066

Showing the first eight; more decompositions exist.
