Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613836, here are decompositions:

3 + 31613833 = 31613836
17 + 31613819 = 31613836
29 + 31613807 = 31613836
53 + 31613783 = 31613836
167 + 31613669 = 31613836
197 + 31613639 = 31613836
257 + 31613579 = 31613836
479 + 31613357 = 31613836

Showing the first eight; more decompositions exist.
