Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618060, here are decompositions:

3 + 31618057 = 31618060
11 + 31618049 = 31618060
17 + 31618043 = 31618060
59 + 31618001 = 31618060
101 + 31617959 = 31618060
107 + 31617953 = 31618060
197 + 31617863 = 31618060
233 + 31617827 = 31618060

Showing the first eight; more decompositions exist.
