Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605504, here are decompositions:

13 + 31605491 = 31605504
61 + 31605443 = 31605504
97 + 31605407 = 31605504
103 + 31605401 = 31605504
127 + 31605377 = 31605504
193 + 31605311 = 31605504
233 + 31605271 = 31605504
241 + 31605263 = 31605504

Showing the first eight; more decompositions exist.
