Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718684, here are decompositions:

11 + 8718673 = 8718684
83 + 8718601 = 8718684
103 + 8718581 = 8718684
113 + 8718571 = 8718684
181 + 8718503 = 8718684
193 + 8718491 = 8718684
197 + 8718487 = 8718684
223 + 8718461 = 8718684

Showing the first eight; more decompositions exist.
