Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978222, here are decompositions:

5 + 978217 = 978222
13 + 978209 = 978222
19 + 978203 = 978222
41 + 978181 = 978222
43 + 978179 = 978222
71 + 978151 = 978222
73 + 978149 = 978222
109 + 978113 = 978222

Showing the first eight; more decompositions exist.
