Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700628, here are decompositions:

29 + 8700599 = 8700628
47 + 8700581 = 8700628
89 + 8700539 = 8700628
107 + 8700521 = 8700628
179 + 8700449 = 8700628
197 + 8700431 = 8700628
227 + 8700401 = 8700628
347 + 8700281 = 8700628

Showing the first eight; more decompositions exist.
