Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605294, here are decompositions:

23 + 31605271 = 31605294
31 + 31605263 = 31605294
37 + 31605257 = 31605294
47 + 31605247 = 31605294
73 + 31605221 = 31605294
113 + 31605181 = 31605294
151 + 31605143 = 31605294
167 + 31605127 = 31605294

Showing the first eight; more decompositions exist.
