Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977128, here are decompositions:

41 + 977087 = 977128
59 + 977069 = 977128
71 + 977057 = 977128
107 + 977021 = 977128
137 + 976991 = 977128
311 + 976817 = 977128
401 + 976727 = 977128
419 + 976709 = 977128

Showing the first eight; more decompositions exist.
