Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700540, here are decompositions:

11 + 8700529 = 8700540
19 + 8700521 = 8700540
29 + 8700511 = 8700540
67 + 8700473 = 8700540
73 + 8700467 = 8700540
83 + 8700457 = 8700540
109 + 8700431 = 8700540
139 + 8700401 = 8700540

Showing the first eight; more decompositions exist.
