Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619124, here are decompositions:

7 + 31619117 = 31619124
83 + 31619041 = 31619124
107 + 31619017 = 31619124
181 + 31618943 = 31619124
223 + 31618901 = 31619124
227 + 31618897 = 31619124
233 + 31618891 = 31619124
241 + 31618883 = 31619124

Showing the first eight; more decompositions exist.
