Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742988, here are decompositions:

11 + 8742977 = 8742988
47 + 8742941 = 8742988
71 + 8742917 = 8742988
101 + 8742887 = 8742988
131 + 8742857 = 8742988
167 + 8742821 = 8742988
311 + 8742677 = 8742988
491 + 8742497 = 8742988

Showing the first eight; more decompositions exist.
