Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496570, here are decompositions:

3 + 31496567 = 31496570
19 + 31496551 = 31496570
31 + 31496539 = 31496570
151 + 31496419 = 31496570
181 + 31496389 = 31496570
199 + 31496371 = 31496570
241 + 31496329 = 31496570
277 + 31496293 = 31496570

Showing the first eight; more decompositions exist.
