Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618062, here are decompositions:

5 + 31618057 = 31618062
13 + 31618049 = 31618062
19 + 31618043 = 31618062
59 + 31618003 = 31618062
61 + 31618001 = 31618062
101 + 31617961 = 31618062
103 + 31617959 = 31618062
109 + 31617953 = 31618062

Showing the first eight; more decompositions exist.
