Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617186, here are decompositions:

5 + 31617181 = 31617186
19 + 31617167 = 31617186
37 + 31617149 = 31617186
53 + 31617133 = 31617186
109 + 31617077 = 31617186
113 + 31617073 = 31617186
137 + 31617049 = 31617186
157 + 31617029 = 31617186

Showing the first eight; more decompositions exist.
