Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527410, here are decompositions:

3 + 31527407 = 31527410
67 + 31527343 = 31527410
157 + 31527253 = 31527410
163 + 31527247 = 31527410
199 + 31527211 = 31527410
457 + 31526953 = 31527410
547 + 31526863 = 31527410
601 + 31526809 = 31527410

Showing the first eight; more decompositions exist.
