Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613710, here are decompositions:

41 + 31613669 = 31613710
71 + 31613639 = 31613710
83 + 31613627 = 31613710
131 + 31613579 = 31613710
197 + 31613513 = 31613710
269 + 31613441 = 31613710
311 + 31613399 = 31613710
353 + 31613357 = 31613710

Showing the first eight; more decompositions exist.
