Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31601392, here are decompositions:

293 + 31601099 = 31601392
509 + 31600883 = 31601392
569 + 31600823 = 31601392
593 + 31600799 = 31601392
659 + 31600733 = 31601392
773 + 31600619 = 31601392
863 + 31600529 = 31601392
881 + 31600511 = 31601392

Showing the first eight; more decompositions exist.
