Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987066, here are decompositions:

5 + 987061 = 987066
13 + 987053 = 987066
23 + 987043 = 987066
37 + 987029 = 987066
43 + 987023 = 987066
53 + 987013 = 987066
83 + 986983 = 987066
103 + 986963 = 987066

Showing the first eight; more decompositions exist.
