Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672972, here are decompositions:

3 + 8672969 = 8672972
19 + 8672953 = 8672972
103 + 8672869 = 8672972
151 + 8672821 = 8672972
181 + 8672791 = 8672972
193 + 8672779 = 8672972
199 + 8672773 = 8672972
241 + 8672731 = 8672972

Showing the first eight; more decompositions exist.
