Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606492, here are decompositions:

23 + 31606469 = 31606492
149 + 31606343 = 31606492
173 + 31606319 = 31606492
179 + 31606313 = 31606492
311 + 31606181 = 31606492
431 + 31606061 = 31606492
443 + 31606049 = 31606492
509 + 31605983 = 31606492

Showing the first eight; more decompositions exist.
