Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618070, here are decompositions:

7 + 31618063 = 31618070
13 + 31618057 = 31618070
67 + 31618003 = 31618070
73 + 31617997 = 31618070
103 + 31617967 = 31618070
109 + 31617961 = 31618070
181 + 31617889 = 31618070
193 + 31617877 = 31618070

Showing the first eight; more decompositions exist.
