Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596524, here are decompositions:

13 + 31596511 = 31596524
331 + 31596193 = 31596524
373 + 31596151 = 31596524
397 + 31596127 = 31596524
457 + 31596067 = 31596524
541 + 31595983 = 31596524
643 + 31595881 = 31596524
691 + 31595833 = 31596524

Showing the first eight; more decompositions exist.
