Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466570, here are decompositions:

7 + 31466563 = 31466570
67 + 31466503 = 31466570
181 + 31466389 = 31466570
229 + 31466341 = 31466570
241 + 31466329 = 31466570
283 + 31466287 = 31466570
307 + 31466263 = 31466570
313 + 31466257 = 31466570

Showing the first eight; more decompositions exist.
