Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606474, here are decompositions:

5 + 31606469 = 31606474
101 + 31606373 = 31606474
131 + 31606343 = 31606474
191 + 31606283 = 31606474
197 + 31606277 = 31606474
293 + 31606181 = 31606474
491 + 31605983 = 31606474
503 + 31605971 = 31606474

Showing the first eight; more decompositions exist.
