Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978280, here are decompositions:

3 + 978277 = 978280
11 + 978269 = 978280
41 + 978239 = 978280
47 + 978233 = 978280
71 + 978209 = 978280
101 + 978179 = 978280
131 + 978149 = 978280
167 + 978113 = 978280

Showing the first eight; more decompositions exist.
