Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606586, here are decompositions:

3 + 31606583 = 31606586
7 + 31606579 = 31606586
43 + 31606543 = 31606586
157 + 31606429 = 31606586
163 + 31606423 = 31606586
199 + 31606387 = 31606586
307 + 31606279 = 31606586
499 + 31606087 = 31606586

Showing the first eight; more decompositions exist.
