Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978600, here are decompositions:

31 + 978569 = 978600
59 + 978541 = 978600
79 + 978521 = 978600
89 + 978511 = 978600
109 + 978491 = 978600
127 + 978473 = 978600
137 + 978463 = 978600
151 + 978449 = 978600

Showing the first eight; more decompositions exist.
