Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708672, here are decompositions:

61 + 8708611 = 8708672
151 + 8708521 = 8708672
163 + 8708509 = 8708672
211 + 8708461 = 8708672
223 + 8708449 = 8708672
499 + 8708173 = 8708672
571 + 8708101 = 8708672
601 + 8708071 = 8708672

Showing the first eight; more decompositions exist.
