Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605674, here are decompositions:

97 + 31605577 = 31605674
103 + 31605571 = 31605674
157 + 31605517 = 31605674
313 + 31605361 = 31605674
547 + 31605127 = 31605674
577 + 31605097 = 31605674
601 + 31605073 = 31605674
673 + 31605001 = 31605674

Showing the first eight; more decompositions exist.
