Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596488, here are decompositions:

97 + 31596391 = 31596488
109 + 31596379 = 31596488
181 + 31596307 = 31596488
337 + 31596151 = 31596488
367 + 31596121 = 31596488
421 + 31596067 = 31596488
439 + 31596049 = 31596488
499 + 31595989 = 31596488

Showing the first eight; more decompositions exist.
