Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596482, here are decompositions:

79 + 31596403 = 31596482
103 + 31596379 = 31596482
331 + 31596151 = 31596482
433 + 31596049 = 31596482
499 + 31595983 = 31596482
601 + 31595881 = 31596482
613 + 31595869 = 31596482
751 + 31595731 = 31596482

Showing the first eight; more decompositions exist.
