Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606882, here are decompositions:

3 + 31606879 = 31606882
53 + 31606829 = 31606882
71 + 31606811 = 31606882
179 + 31606703 = 31606882
191 + 31606691 = 31606882
239 + 31606643 = 31606882
353 + 31606529 = 31606882
383 + 31606499 = 31606882

Showing the first eight; more decompositions exist.
