Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606502, here are decompositions:

3 + 31606499 = 31606502
73 + 31606429 = 31606502
79 + 31606423 = 31606502
163 + 31606339 = 31606502
223 + 31606279 = 31606502
241 + 31606261 = 31606502
691 + 31605811 = 31606502
883 + 31605619 = 31606502

Showing the first eight; more decompositions exist.
