Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725782, here are decompositions:

83 + 8725699 = 8725782
101 + 8725681 = 8725782
113 + 8725669 = 8725782
139 + 8725643 = 8725782
151 + 8725631 = 8725782
173 + 8725609 = 8725782
211 + 8725571 = 8725782
251 + 8725531 = 8725782

Showing the first eight; more decompositions exist.
