Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613834, here are decompositions:

37 + 31613797 = 31613834
211 + 31613623 = 31613834
283 + 31613551 = 31613834
397 + 31613437 = 31613834
433 + 31613401 = 31613834
457 + 31613377 = 31613834
607 + 31613227 = 31613834
643 + 31613191 = 31613834

Showing the first eight; more decompositions exist.
