Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606706, here are decompositions:

3 + 31606703 = 31606706
127 + 31606579 = 31606706
163 + 31606543 = 31606706
277 + 31606429 = 31606706
283 + 31606423 = 31606706
337 + 31606369 = 31606706
367 + 31606339 = 31606706
409 + 31606297 = 31606706

Showing the first eight; more decompositions exist.
