Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681250, here are decompositions:

7 + 8681243 = 8681250
29 + 8681221 = 8681250
37 + 8681213 = 8681250
43 + 8681207 = 8681250
59 + 8681191 = 8681250
73 + 8681177 = 8681250
139 + 8681111 = 8681250
173 + 8681077 = 8681250

Showing the first eight; more decompositions exist.
