Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613272, here are decompositions:

23 + 31613249 = 31613272
29 + 31613243 = 31613272
101 + 31613171 = 31613272
281 + 31612991 = 31613272
311 + 31612961 = 31613272
359 + 31612913 = 31613272
419 + 31612853 = 31613272
653 + 31612619 = 31613272

Showing the first eight; more decompositions exist.
