Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708020, here are decompositions:

3 + 8708017 = 8708020
17 + 8708003 = 8708020
23 + 8707997 = 8708020
137 + 8707883 = 8708020
179 + 8707841 = 8708020
227 + 8707793 = 8708020
239 + 8707781 = 8708020
257 + 8707763 = 8708020

Showing the first eight; more decompositions exist.
