Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708218, here are decompositions:

17 + 8708201 = 8708218
59 + 8708159 = 8708218
89 + 8708129 = 8708218
131 + 8708087 = 8708218
137 + 8708081 = 8708218
149 + 8708069 = 8708218
179 + 8708039 = 8708218
401 + 8707817 = 8708218

Showing the first eight; more decompositions exist.
