Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978288, here are decompositions:

5 + 978283 = 978288
11 + 978277 = 978288
19 + 978269 = 978288
71 + 978217 = 978288
79 + 978209 = 978288
107 + 978181 = 978288
109 + 978179 = 978288
131 + 978157 = 978288

Showing the first eight; more decompositions exist.
