Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618026, here are decompositions:

23 + 31618003 = 31618026
29 + 31617997 = 31618026
59 + 31617967 = 31618026
67 + 31617959 = 31618026
73 + 31617953 = 31618026
127 + 31617899 = 31618026
137 + 31617889 = 31618026
149 + 31617877 = 31618026

Showing the first eight; more decompositions exist.
