Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978284, here are decompositions:

7 + 978277 = 978284
61 + 978223 = 978284
67 + 978217 = 978284
103 + 978181 = 978284
127 + 978157 = 978284
193 + 978091 = 978284
211 + 978073 = 978284
277 + 978007 = 978284

Showing the first eight; more decompositions exist.
