Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606836, here are decompositions:

7 + 31606829 = 31606836
83 + 31606753 = 31606836
109 + 31606727 = 31606836
139 + 31606697 = 31606836
179 + 31606657 = 31606836
193 + 31606643 = 31606836
257 + 31606579 = 31606836
277 + 31606559 = 31606836

Showing the first eight; more decompositions exist.
