Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537834, here are decompositions:

11 + 31537823 = 31537834
113 + 31537721 = 31537834
353 + 31537481 = 31537834
401 + 31537433 = 31537834
443 + 31537391 = 31537834
521 + 31537313 = 31537834
563 + 31537271 = 31537834
683 + 31537151 = 31537834

Showing the first eight; more decompositions exist.
