Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977390, here are decompositions:

31 + 977359 = 977390
67 + 977323 = 977390
151 + 977239 = 977390
157 + 977233 = 977390
181 + 977209 = 977390
199 + 977191 = 977390
223 + 977167 = 977390
241 + 977149 = 977390

Showing the first eight; more decompositions exist.
