Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606510, here are decompositions:

11 + 31606499 = 31606510
17 + 31606493 = 31606510
41 + 31606469 = 31606510
113 + 31606397 = 31606510
137 + 31606373 = 31606510
167 + 31606343 = 31606510
179 + 31606331 = 31606510
191 + 31606319 = 31606510

Showing the first eight; more decompositions exist.
