Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978318, here are decompositions:

31 + 978287 = 978318
41 + 978277 = 978318
79 + 978239 = 978318
101 + 978217 = 978318
109 + 978209 = 978318
137 + 978181 = 978318
139 + 978179 = 978318
167 + 978151 = 978318

Showing the first eight; more decompositions exist.
