Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619176, here are decompositions:

5 + 31619171 = 31619176
47 + 31619129 = 31619176
53 + 31619123 = 31619176
59 + 31619117 = 31619176
167 + 31619009 = 31619176
227 + 31618949 = 31619176
233 + 31618943 = 31619176
293 + 31618883 = 31619176

Showing the first eight; more decompositions exist.
