Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618676, here are decompositions:

7 + 31618669 = 31618676
13 + 31618663 = 31618676
43 + 31618633 = 31618676
79 + 31618597 = 31618676
97 + 31618579 = 31618676
109 + 31618567 = 31618676
127 + 31618549 = 31618676
157 + 31618519 = 31618676

Showing the first eight; more decompositions exist.
