Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725672, here are decompositions:

3 + 8725669 = 8725672
29 + 8725643 = 8725672
41 + 8725631 = 8725672
101 + 8725571 = 8725672
149 + 8725523 = 8725672
173 + 8725499 = 8725672
191 + 8725481 = 8725672
251 + 8725421 = 8725672

Showing the first eight; more decompositions exist.
