Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978444, here are decompositions:

17 + 978427 = 978444
31 + 978413 = 978444
41 + 978403 = 978444
97 + 978347 = 978444
101 + 978343 = 978444
107 + 978337 = 978444
157 + 978287 = 978444
167 + 978277 = 978444

Showing the first eight; more decompositions exist.
