Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605424, here are decompositions:

5 + 31605419 = 31605424
17 + 31605407 = 31605424
23 + 31605401 = 31605424
47 + 31605377 = 31605424
113 + 31605311 = 31605424
167 + 31605257 = 31605424
281 + 31605143 = 31605424
353 + 31605071 = 31605424

Showing the first eight; more decompositions exist.
