Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981064, here are decompositions:

3 + 981061 = 981064
41 + 981023 = 981064
47 + 981017 = 981064
53 + 981011 = 981064
101 + 980963 = 981064
107 + 980957 = 981064
167 + 980897 = 981064
233 + 980831 = 981064

Showing the first eight; more decompositions exist.
