Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522510, here are decompositions:

17 + 31522493 = 31522510
59 + 31522451 = 31522510
137 + 31522373 = 31522510
179 + 31522331 = 31522510
197 + 31522313 = 31522510
233 + 31522277 = 31522510
263 + 31522247 = 31522510
269 + 31522241 = 31522510

Showing the first eight; more decompositions exist.
