Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977200, here are decompositions:

17 + 977183 = 977200
53 + 977147 = 977200
113 + 977087 = 977200
131 + 977069 = 977200
179 + 977021 = 977200
281 + 976919 = 977200
317 + 976883 = 977200
347 + 976853 = 977200

Showing the first eight; more decompositions exist.
