Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708140, here are decompositions:

11 + 8708129 = 8708140
47 + 8708093 = 8708140
53 + 8708087 = 8708140
59 + 8708081 = 8708140
71 + 8708069 = 8708140
101 + 8708039 = 8708140
137 + 8708003 = 8708140
257 + 8707883 = 8708140

Showing the first eight; more decompositions exist.
