Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618014, here are decompositions:

11 + 31618003 = 31618014
13 + 31618001 = 31618014
17 + 31617997 = 31618014
47 + 31617967 = 31618014
53 + 31617961 = 31618014
61 + 31617953 = 31618014
73 + 31617941 = 31618014
137 + 31617877 = 31618014

Showing the first eight; more decompositions exist.
