Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978372, here are decompositions:

13 + 978359 = 978372
23 + 978349 = 978372
29 + 978343 = 978372
89 + 978283 = 978372
103 + 978269 = 978372
139 + 978233 = 978372
149 + 978223 = 978372
163 + 978209 = 978372

Showing the first eight; more decompositions exist.
