Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700984, here are decompositions:

31 + 8700953 = 8700984
37 + 8700947 = 8700984
43 + 8700941 = 8700984
53 + 8700931 = 8700984
73 + 8700911 = 8700984
113 + 8700871 = 8700984
151 + 8700833 = 8700984
157 + 8700827 = 8700984

Showing the first eight; more decompositions exist.
