Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527668, here are decompositions:

127 + 31527541 = 31527668
421 + 31527247 = 31527668
457 + 31527211 = 31527668
727 + 31526941 = 31527668
769 + 31526899 = 31527668
787 + 31526881 = 31527668
859 + 31526809 = 31527668
877 + 31526791 = 31527668

Showing the first eight; more decompositions exist.
