Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527494, here are decompositions:

3 + 31527491 = 31527494
13 + 31527481 = 31527494
151 + 31527343 = 31527494
241 + 31527253 = 31527494
283 + 31527211 = 31527494
337 + 31527157 = 31527494
541 + 31526953 = 31527494
601 + 31526893 = 31527494

Showing the first eight; more decompositions exist.
