Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978178, here are decompositions:

29 + 978149 = 978178
101 + 978077 = 978178
107 + 978071 = 978178
137 + 978041 = 978178
167 + 978011 = 978178
251 + 977927 = 978178
281 + 977897 = 978178
317 + 977861 = 978178

Showing the first eight; more decompositions exist.
