Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605536, here are decompositions:

19 + 31605517 = 31605536
97 + 31605439 = 31605536
307 + 31605229 = 31605536
367 + 31605169 = 31605536
397 + 31605139 = 31605536
409 + 31605127 = 31605536
439 + 31605097 = 31605536
463 + 31605073 = 31605536

Showing the first eight; more decompositions exist.
