Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672736, here are decompositions:

5 + 8672731 = 8672736
13 + 8672723 = 8672736
29 + 8672707 = 8672736
89 + 8672647 = 8672736
97 + 8672639 = 8672736
139 + 8672597 = 8672736
173 + 8672563 = 8672736
197 + 8672539 = 8672736

Showing the first eight; more decompositions exist.
