Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605602, here are decompositions:

19 + 31605583 = 31605602
31 + 31605571 = 31605602
163 + 31605439 = 31605602
241 + 31605361 = 31605602
283 + 31605319 = 31605602
331 + 31605271 = 31605602
373 + 31605229 = 31605602
421 + 31605181 = 31605602

Showing the first eight; more decompositions exist.
