Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978224, here are decompositions:

7 + 978217 = 978224
43 + 978181 = 978224
67 + 978157 = 978224
73 + 978151 = 978224
151 + 978073 = 978224
157 + 978067 = 978224
193 + 978031 = 978224
223 + 978001 = 978224

Showing the first eight; more decompositions exist.
