Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977998, here are decompositions:

71 + 977927 = 977998
101 + 977897 = 977998
137 + 977861 = 977998
149 + 977849 = 977998
167 + 977831 = 977998
179 + 977819 = 977998
251 + 977747 = 977998
317 + 977681 = 977998

Showing the first eight; more decompositions exist.
