Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606616, here are decompositions:

37 + 31606579 = 31606616
73 + 31606543 = 31606616
79 + 31606537 = 31606616
193 + 31606423 = 31606616
229 + 31606387 = 31606616
277 + 31606339 = 31606616
337 + 31606279 = 31606616
739 + 31605877 = 31606616

Showing the first eight; more decompositions exist.
