Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619050, here are decompositions:

41 + 31619009 = 31619050
59 + 31618991 = 31619050
101 + 31618949 = 31619050
107 + 31618943 = 31619050
149 + 31618901 = 31619050
167 + 31618883 = 31619050
179 + 31618871 = 31619050
227 + 31618823 = 31619050

Showing the first eight; more decompositions exist.
