Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606412, here are decompositions:

31 + 31606381 = 31606412
43 + 31606369 = 31606412
73 + 31606339 = 31606412
151 + 31606261 = 31606412
499 + 31605913 = 31606412
601 + 31605811 = 31606412
631 + 31605781 = 31606412
829 + 31605583 = 31606412

Showing the first eight; more decompositions exist.
