Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991070, here are decompositions:

7 + 991063 = 991070
13 + 991057 = 991070
43 + 991027 = 991070
61 + 991009 = 991070
97 + 990973 = 991070
103 + 990967 = 991070
109 + 990961 = 991070
181 + 990889 = 991070

Showing the first eight; more decompositions exist.
