Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678000, here are decompositions:

7 + 8677993 = 8678000
109 + 8677891 = 8678000
229 + 8677771 = 8678000
241 + 8677759 = 8678000
277 + 8677723 = 8678000
337 + 8677663 = 8678000
349 + 8677651 = 8678000
523 + 8677477 = 8678000

Showing the first eight; more decompositions exist.
