Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987104, here are decompositions:

3 + 987101 = 987104
7 + 987097 = 987104
37 + 987067 = 987104
43 + 987061 = 987104
61 + 987043 = 987104
163 + 986941 = 987104
337 + 986767 = 987104
367 + 986737 = 987104

Showing the first eight; more decompositions exist.
