Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978432, here are decompositions:

5 + 978427 = 978432
19 + 978413 = 978432
29 + 978403 = 978432
43 + 978389 = 978432
73 + 978359 = 978432
83 + 978349 = 978432
89 + 978343 = 978432
109 + 978323 = 978432

Showing the first eight; more decompositions exist.
