Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978972, here are decompositions:

41 + 978931 = 978972
89 + 978883 = 978972
101 + 978871 = 978972
109 + 978863 = 978972
151 + 978821 = 978972
173 + 978799 = 978972
199 + 978773 = 978972
223 + 978749 = 978972

Showing the first eight; more decompositions exist.
