Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978584, here are decompositions:

43 + 978541 = 978584
73 + 978511 = 978584
127 + 978457 = 978584
157 + 978427 = 978584
181 + 978403 = 978584
241 + 978343 = 978584
307 + 978277 = 978584
367 + 978217 = 978584

Showing the first eight; more decompositions exist.
