Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527548, here are decompositions:

7 + 31527541 = 31527548
67 + 31527481 = 31527548
271 + 31527277 = 31527548
337 + 31527211 = 31527548
397 + 31527151 = 31527548
439 + 31527109 = 31527548
607 + 31526941 = 31527548
739 + 31526809 = 31527548

Showing the first eight; more decompositions exist.
