Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732988, here are decompositions:

31 + 8732957 = 8732988
67 + 8732921 = 8732988
101 + 8732887 = 8732988
109 + 8732879 = 8732988
127 + 8732861 = 8732988
149 + 8732839 = 8732988
157 + 8732831 = 8732988
181 + 8732807 = 8732988

Showing the first eight; more decompositions exist.
