Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977970, here are decompositions:

43 + 977927 = 977970
47 + 977923 = 977970
73 + 977897 = 977970
89 + 977881 = 977970
109 + 977861 = 977970
139 + 977831 = 977970
151 + 977819 = 977970
157 + 977813 = 977970

Showing the first eight; more decompositions exist.
