Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987086, here are decompositions:

3 + 987083 = 987086
7 + 987079 = 987086
19 + 987067 = 987086
43 + 987043 = 987086
73 + 987013 = 987086
97 + 986989 = 987086
103 + 986983 = 987086
127 + 986959 = 987086

Showing the first eight; more decompositions exist.
