Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619236, here are decompositions:

23 + 31619213 = 31619236
29 + 31619207 = 31619236
53 + 31619183 = 31619236
59 + 31619177 = 31619236
107 + 31619129 = 31619236
113 + 31619123 = 31619236
227 + 31619009 = 31619236
293 + 31618943 = 31619236

Showing the first eight; more decompositions exist.
