Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606550, here are decompositions:

7 + 31606543 = 31606550
13 + 31606537 = 31606550
127 + 31606423 = 31606550
139 + 31606411 = 31606550
163 + 31606387 = 31606550
181 + 31606369 = 31606550
211 + 31606339 = 31606550
271 + 31606279 = 31606550

Showing the first eight; more decompositions exist.
