Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606082, here are decompositions:

3 + 31606079 = 31606082
31 + 31606051 = 31606082
271 + 31605811 = 31606082
463 + 31605619 = 31606082
499 + 31605583 = 31606082
643 + 31605439 = 31606082
733 + 31605349 = 31606082
811 + 31605271 = 31606082

Showing the first eight; more decompositions exist.
