Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978998, here are decompositions:

67 + 978931 = 978998
127 + 978871 = 978998
199 + 978799 = 978998
271 + 978727 = 978998
379 + 978619 = 978998
457 + 978541 = 978998
487 + 978511 = 978998
541 + 978457 = 978998

Showing the first eight; more decompositions exist.
