Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978012, here are decompositions:

5 + 978007 = 978012
11 + 978001 = 978012
41 + 977971 = 978012
89 + 977923 = 978012
131 + 977881 = 978012
151 + 977861 = 978012
163 + 977849 = 978012
181 + 977831 = 978012

Showing the first eight; more decompositions exist.
