Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527396, here are decompositions:

7 + 31527389 = 31527396
53 + 31527343 = 31527396
73 + 31527323 = 31527396
79 + 31527317 = 31527396
149 + 31527247 = 31527396
163 + 31527233 = 31527396
223 + 31527173 = 31527396
239 + 31527157 = 31527396

Showing the first eight; more decompositions exist.
