Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606316, here are decompositions:

3 + 31606313 = 31606316
19 + 31606297 = 31606316
37 + 31606279 = 31606316
229 + 31606087 = 31606316
439 + 31605877 = 31606316
619 + 31605697 = 31606316
733 + 31605583 = 31606316
739 + 31605577 = 31606316

Showing the first eight; more decompositions exist.
