Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527278, here are decompositions:

31 + 31527247 = 31527278
67 + 31527211 = 31527278
127 + 31527151 = 31527278
337 + 31526941 = 31527278
379 + 31526899 = 31527278
397 + 31526881 = 31527278
487 + 31526791 = 31527278
547 + 31526731 = 31527278

Showing the first eight; more decompositions exist.
