Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977980, here are decompositions:

53 + 977927 = 977980
83 + 977897 = 977980
131 + 977849 = 977980
149 + 977831 = 977980
167 + 977813 = 977980
233 + 977747 = 977980
257 + 977723 = 977980
389 + 977591 = 977980

Showing the first eight; more decompositions exist.
