Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628972, here are decompositions:

5 + 8628967 = 8628972
59 + 8628913 = 8628972
73 + 8628899 = 8628972
83 + 8628889 = 8628972
89 + 8628883 = 8628972
113 + 8628859 = 8628972
173 + 8628799 = 8628972
181 + 8628791 = 8628972

Showing the first eight; more decompositions exist.
