Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987146, here are decompositions:

3 + 987143 = 987146
19 + 987127 = 987146
67 + 987079 = 987146
79 + 987067 = 987146
103 + 987043 = 987146
157 + 986989 = 987146
163 + 986983 = 987146
367 + 986779 = 987146

Showing the first eight; more decompositions exist.
