Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605962, here are decompositions:

139 + 31605823 = 31605962
151 + 31605811 = 31605962
181 + 31605781 = 31605962
379 + 31605583 = 31605962
523 + 31605439 = 31605962
601 + 31605361 = 31605962
613 + 31605349 = 31605962
643 + 31605319 = 31605962

Showing the first eight; more decompositions exist.
