Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619022, here are decompositions:

5 + 31619017 = 31619022
13 + 31619009 = 31619022
23 + 31618999 = 31619022
31 + 31618991 = 31619022
41 + 31618981 = 31619022
73 + 31618949 = 31619022
79 + 31618943 = 31619022
131 + 31618891 = 31619022

Showing the first eight; more decompositions exist.
