Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 969878, here are decompositions:

157 + 969721 = 969878
199 + 969679 = 969878
211 + 969667 = 969878
241 + 969637 = 969878
397 + 969481 = 969878
421 + 969457 = 969878
457 + 969421 = 969878
577 + 969301 = 969878

Showing the first eight; more decompositions exist.
