Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670578, here are decompositions:

19 + 8670559 = 8670578
79 + 8670499 = 8670578
97 + 8670481 = 8670578
127 + 8670451 = 8670578
181 + 8670397 = 8670578
277 + 8670301 = 8670578
421 + 8670157 = 8670578
541 + 8670037 = 8670578

Showing the first eight; more decompositions exist.
