Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978168, here are decompositions:

11 + 978157 = 978168
17 + 978151 = 978168
19 + 978149 = 978168
89 + 978079 = 978168
97 + 978071 = 978168
101 + 978067 = 978168
127 + 978041 = 978168
131 + 978037 = 978168

Showing the first eight; more decompositions exist.
