Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700942, here are decompositions:

11 + 8700931 = 8700942
31 + 8700911 = 8700942
71 + 8700871 = 8700942
73 + 8700869 = 8700942
109 + 8700833 = 8700942
149 + 8700793 = 8700942
191 + 8700751 = 8700942
233 + 8700709 = 8700942

Showing the first eight; more decompositions exist.
