Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978212, here are decompositions:

3 + 978209 = 978212
31 + 978181 = 978212
61 + 978151 = 978212
139 + 978073 = 978212
163 + 978049 = 978212
181 + 978031 = 978212
211 + 978001 = 978212
241 + 977971 = 978212

Showing the first eight; more decompositions exist.
