Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606396, here are decompositions:

23 + 31606373 = 31606396
53 + 31606343 = 31606396
83 + 31606313 = 31606396
113 + 31606283 = 31606396
317 + 31606079 = 31606396
347 + 31606049 = 31606396
443 + 31605953 = 31606396
467 + 31605929 = 31606396

Showing the first eight; more decompositions exist.
