Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700394, here are decompositions:

11 + 8700383 = 8700394
41 + 8700353 = 8700394
107 + 8700287 = 8700394
113 + 8700281 = 8700394
137 + 8700257 = 8700394
233 + 8700161 = 8700394
281 + 8700113 = 8700394
347 + 8700047 = 8700394

Showing the first eight; more decompositions exist.
