Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619010, here are decompositions:

11 + 31618999 = 31619010
19 + 31618991 = 31619010
29 + 31618981 = 31619010
61 + 31618949 = 31619010
67 + 31618943 = 31619010
109 + 31618901 = 31619010
113 + 31618897 = 31619010
127 + 31618883 = 31619010

Showing the first eight; more decompositions exist.
