Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606382, here are decompositions:

13 + 31606369 = 31606382
43 + 31606339 = 31606382
103 + 31606279 = 31606382
331 + 31606051 = 31606382
571 + 31605811 = 31606382
601 + 31605781 = 31606382
811 + 31605571 = 31606382
1021 + 31605361 = 31606382

Showing the first eight; more decompositions exist.
