Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618692, here are decompositions:

11 + 31618681 = 31618692
23 + 31618669 = 31618692
29 + 31618663 = 31618692
59 + 31618633 = 31618692
71 + 31618621 = 31618692
113 + 31618579 = 31618692
173 + 31618519 = 31618692
229 + 31618463 = 31618692

Showing the first eight; more decompositions exist.
