Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978240, here are decompositions:

7 + 978233 = 978240
17 + 978223 = 978240
23 + 978217 = 978240
31 + 978209 = 978240
37 + 978203 = 978240
59 + 978181 = 978240
61 + 978179 = 978240
83 + 978157 = 978240

Showing the first eight; more decompositions exist.
