Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977218, here are decompositions:

71 + 977147 = 977218
131 + 977087 = 977218
149 + 977069 = 977218
197 + 977021 = 977218
227 + 976991 = 977218
401 + 976817 = 977218
419 + 976799 = 977218
491 + 976727 = 977218

Showing the first eight; more decompositions exist.
