Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623102, here are decompositions:

41 + 31623061 = 31623102
61 + 31623041 = 31623102
79 + 31623023 = 31623102
151 + 31622951 = 31623102
163 + 31622939 = 31623102
179 + 31622923 = 31623102
239 + 31622863 = 31623102
293 + 31622809 = 31623102

Showing the first eight; more decompositions exist.
