Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977868, here are decompositions:

7 + 977861 = 977868
19 + 977849 = 977868
37 + 977831 = 977868
107 + 977761 = 977868
149 + 977719 = 977868
197 + 977671 = 977868
239 + 977629 = 977868
257 + 977611 = 977868

Showing the first eight; more decompositions exist.
