Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605234, here are decompositions:

5 + 31605229 = 31605234
13 + 31605221 = 31605234
53 + 31605181 = 31605234
107 + 31605127 = 31605234
137 + 31605097 = 31605234
163 + 31605071 = 31605234
233 + 31605001 = 31605234
431 + 31604803 = 31605234

Showing the first eight; more decompositions exist.
