Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987994, here are decompositions:

3 + 987991 = 987994
11 + 987983 = 987994
23 + 987971 = 987994
53 + 987941 = 987994
83 + 987911 = 987994
173 + 987821 = 987994
191 + 987803 = 987994
197 + 987797 = 987994

Showing the first eight; more decompositions exist.
