Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725660, here are decompositions:

3 + 8725657 = 8725660
17 + 8725643 = 8725660
29 + 8725631 = 8725660
89 + 8725571 = 8725660
113 + 8725547 = 8725660
137 + 8725523 = 8725660
149 + 8725511 = 8725660
179 + 8725481 = 8725660

Showing the first eight; more decompositions exist.
