Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537934, here are decompositions:

13 + 31537921 = 31537934
31 + 31537903 = 31537934
73 + 31537861 = 31537934
97 + 31537837 = 31537934
193 + 31537741 = 31537934
331 + 31537603 = 31537934
457 + 31537477 = 31537934
607 + 31537327 = 31537934

Showing the first eight; more decompositions exist.
