Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607124, here are decompositions:

23 + 31607101 = 31607124
37 + 31607087 = 31607124
127 + 31606997 = 31607124
151 + 31606973 = 31607124
167 + 31606957 = 31607124
173 + 31606951 = 31607124
181 + 31606943 = 31607124
193 + 31606931 = 31607124

Showing the first eight; more decompositions exist.
