Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606252, here are decompositions:

71 + 31606181 = 31606252
173 + 31606079 = 31606252
191 + 31606061 = 31606252
269 + 31605983 = 31606252
281 + 31605971 = 31606252
443 + 31605809 = 31606252
449 + 31605803 = 31606252
479 + 31605773 = 31606252

Showing the first eight; more decompositions exist.
