Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527134, here are decompositions:

3 + 31527131 = 31527134
181 + 31526953 = 31527134
193 + 31526941 = 31527134
241 + 31526893 = 31527134
271 + 31526863 = 31527134
421 + 31526713 = 31527134
487 + 31526647 = 31527134
571 + 31526563 = 31527134

Showing the first eight; more decompositions exist.
