Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606534, here are decompositions:

5 + 31606529 = 31606534
17 + 31606517 = 31606534
41 + 31606493 = 31606534
137 + 31606397 = 31606534
191 + 31606343 = 31606534
251 + 31606283 = 31606534
257 + 31606277 = 31606534
347 + 31606187 = 31606534

Showing the first eight; more decompositions exist.
