Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701028, here are decompositions:

19 + 8701009 = 8701028
97 + 8700931 = 8701028
157 + 8700871 = 8701028
211 + 8700817 = 8701028
229 + 8700799 = 8701028
277 + 8700751 = 8701028
307 + 8700721 = 8701028
331 + 8700697 = 8701028

Showing the first eight; more decompositions exist.
