Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605702, here are decompositions:

5 + 31605697 = 31605702
13 + 31605689 = 31605702
83 + 31605619 = 31605702
109 + 31605593 = 31605702
131 + 31605571 = 31605702
151 + 31605551 = 31605702
211 + 31605491 = 31605702
263 + 31605439 = 31605702

Showing the first eight; more decompositions exist.
