Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725648, here are decompositions:

5 + 8725643 = 8725648
17 + 8725631 = 8725648
101 + 8725547 = 8725648
137 + 8725511 = 8725648
149 + 8725499 = 8725648
167 + 8725481 = 8725648
227 + 8725421 = 8725648
251 + 8725397 = 8725648

Showing the first eight; more decompositions exist.
