Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618324, here are decompositions:

5 + 31618319 = 31618324
113 + 31618211 = 31618324
131 + 31618193 = 31618324
137 + 31618187 = 31618324
191 + 31618133 = 31618324
197 + 31618127 = 31618324
263 + 31618061 = 31618324
281 + 31618043 = 31618324

Showing the first eight; more decompositions exist.
