Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978884, here are decompositions:

13 + 978871 = 978884
31 + 978853 = 978884
157 + 978727 = 978884
241 + 978643 = 978884
373 + 978511 = 978884
421 + 978463 = 978884
457 + 978427 = 978884
541 + 978343 = 978884

Showing the first eight; more decompositions exist.
