Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978018, here are decompositions:

7 + 978011 = 978018
11 + 978007 = 978018
17 + 978001 = 978018
47 + 977971 = 978018
137 + 977881 = 978018
157 + 977861 = 978018
199 + 977819 = 978018
227 + 977791 = 978018

Showing the first eight; more decompositions exist.
