Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725630, here are decompositions:

3 + 8725627 = 8725630
59 + 8725571 = 8725630
83 + 8725547 = 8725630
107 + 8725523 = 8725630
131 + 8725499 = 8725630
149 + 8725481 = 8725630
167 + 8725463 = 8725630
233 + 8725397 = 8725630

Showing the first eight; more decompositions exist.
