Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619052, here are decompositions:

11 + 31619041 = 31619052
43 + 31619009 = 31619052
53 + 31618999 = 31619052
61 + 31618991 = 31619052
71 + 31618981 = 31619052
103 + 31618949 = 31619052
109 + 31618943 = 31619052
151 + 31618901 = 31619052

Showing the first eight; more decompositions exist.
