Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627972, here are decompositions:

19 + 8627953 = 8627972
61 + 8627911 = 8627972
79 + 8627893 = 8627972
139 + 8627833 = 8627972
163 + 8627809 = 8627972
271 + 8627701 = 8627972
439 + 8627533 = 8627972
499 + 8627473 = 8627972

Showing the first eight; more decompositions exist.
