Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725800, here are decompositions:

43 + 8725757 = 8725800
67 + 8725733 = 8725800
101 + 8725699 = 8725800
131 + 8725669 = 8725800
157 + 8725643 = 8725800
173 + 8725627 = 8725800
179 + 8725621 = 8725800
191 + 8725609 = 8725800

Showing the first eight; more decompositions exist.
