Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978228, here are decompositions:

5 + 978223 = 978228
11 + 978217 = 978228
19 + 978209 = 978228
47 + 978181 = 978228
71 + 978157 = 978228
79 + 978149 = 978228
137 + 978091 = 978228
149 + 978079 = 978228

Showing the first eight; more decompositions exist.
