Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613564, here are decompositions:

13 + 31613551 = 31613564
127 + 31613437 = 31613564
163 + 31613401 = 31613564
181 + 31613383 = 31613564
223 + 31613341 = 31613564
337 + 31613227 = 31613564
373 + 31613191 = 31613564
421 + 31613143 = 31613564

Showing the first eight; more decompositions exist.
