Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619032, here are decompositions:

23 + 31619009 = 31619032
41 + 31618991 = 31619032
83 + 31618949 = 31619032
89 + 31618943 = 31619032
131 + 31618901 = 31619032
149 + 31618883 = 31619032
251 + 31618781 = 31619032
281 + 31618751 = 31619032

Showing the first eight; more decompositions exist.
