Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623174, here are decompositions:

5 + 31623169 = 31623174
7 + 31623167 = 31623174
53 + 31623121 = 31623174
61 + 31623113 = 31623174
113 + 31623061 = 31623174
127 + 31623047 = 31623174
151 + 31623023 = 31623174
223 + 31622951 = 31623174

Showing the first eight; more decompositions exist.
