Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527420, here are decompositions:

7 + 31527413 = 31527420
13 + 31527407 = 31527420
31 + 31527389 = 31527420
97 + 31527323 = 31527420
103 + 31527317 = 31527420
109 + 31527311 = 31527420
167 + 31527253 = 31527420
173 + 31527247 = 31527420

Showing the first eight; more decompositions exist.
