Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611324, here are decompositions:

5 + 31611319 = 31611324
13 + 31611311 = 31611324
23 + 31611301 = 31611324
53 + 31611271 = 31611324
137 + 31611187 = 31611324
197 + 31611127 = 31611324
211 + 31611113 = 31611324
223 + 31611101 = 31611324

Showing the first eight; more decompositions exist.
