Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725678, here are decompositions:

47 + 8725631 = 8725678
107 + 8725571 = 8725678
131 + 8725547 = 8725678
167 + 8725511 = 8725678
179 + 8725499 = 8725678
197 + 8725481 = 8725678
257 + 8725421 = 8725678
281 + 8725397 = 8725678

Showing the first eight; more decompositions exist.
