Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643506, here are decompositions:

19 + 8643487 = 8643506
73 + 8643433 = 8643506
97 + 8643409 = 8643506
139 + 8643367 = 8643506
163 + 8643343 = 8643506
199 + 8643307 = 8643506
283 + 8643223 = 8643506
307 + 8643199 = 8643506

Showing the first eight; more decompositions exist.
