Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618976, here are decompositions:

79 + 31618897 = 31618976
97 + 31618879 = 31618976
127 + 31618849 = 31618976
157 + 31618819 = 31618976
199 + 31618777 = 31618976
223 + 31618753 = 31618976
283 + 31618693 = 31618976
307 + 31618669 = 31618976

Showing the first eight; more decompositions exist.
