Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613536, here are decompositions:

23 + 31613513 = 31613536
137 + 31613399 = 31613536
179 + 31613357 = 31613536
293 + 31613243 = 31613536
419 + 31613117 = 31613536
509 + 31613027 = 31613536
683 + 31612853 = 31613536
797 + 31612739 = 31613536

Showing the first eight; more decompositions exist.
