Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618674, here are decompositions:

5 + 31618669 = 31618674
11 + 31618663 = 31618674
37 + 31618637 = 31618674
41 + 31618633 = 31618674
53 + 31618621 = 31618674
107 + 31618567 = 31618674
127 + 31618547 = 31618674
211 + 31618463 = 31618674

Showing the first eight; more decompositions exist.
