Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978158, here are decompositions:

7 + 978151 = 978158
67 + 978091 = 978158
79 + 978079 = 978158
109 + 978049 = 978158
127 + 978031 = 978158
151 + 978007 = 978158
157 + 978001 = 978158
277 + 977881 = 978158

Showing the first eight; more decompositions exist.
