Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527516, here are decompositions:

17 + 31527499 = 31527516
19 + 31527497 = 31527516
103 + 31527413 = 31527516
109 + 31527407 = 31527516
127 + 31527389 = 31527516
173 + 31527343 = 31527516
193 + 31527323 = 31527516
199 + 31527317 = 31527516

Showing the first eight; more decompositions exist.
