Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978236, here are decompositions:

3 + 978233 = 978236
13 + 978223 = 978236
19 + 978217 = 978236
79 + 978157 = 978236
157 + 978079 = 978236
163 + 978073 = 978236
199 + 978037 = 978236
229 + 978007 = 978236

Showing the first eight; more decompositions exist.
