Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708120, here are decompositions:

19 + 8708101 = 8708120
103 + 8708017 = 8708120
151 + 8707969 = 8708120
181 + 8707939 = 8708120
241 + 8707879 = 8708120
277 + 8707843 = 8708120
283 + 8707837 = 8708120
367 + 8707753 = 8708120

Showing the first eight; more decompositions exist.
