Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987084, here are decompositions:

5 + 987079 = 987084
17 + 987067 = 987084
23 + 987061 = 987084
31 + 987053 = 987084
41 + 987043 = 987084
61 + 987023 = 987084
71 + 987013 = 987084
101 + 986983 = 987084

Showing the first eight; more decompositions exist.
