Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618926, here are decompositions:

29 + 31618897 = 31618926
43 + 31618883 = 31618926
47 + 31618879 = 31618926
103 + 31618823 = 31618926
107 + 31618819 = 31618926
149 + 31618777 = 31618926
173 + 31618753 = 31618926
223 + 31618703 = 31618926

Showing the first eight; more decompositions exist.
