Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987070, here are decompositions:

3 + 987067 = 987070
17 + 987053 = 987070
41 + 987029 = 987070
47 + 987023 = 987070
89 + 986981 = 987070
107 + 986963 = 987070
137 + 986933 = 987070
167 + 986903 = 987070

Showing the first eight; more decompositions exist.
