Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987210, here are decompositions:

11 + 987199 = 987210
17 + 987193 = 987210
19 + 987191 = 987210
67 + 987143 = 987210
83 + 987127 = 987210
109 + 987101 = 987210
113 + 987097 = 987210
127 + 987083 = 987210

Showing the first eight; more decompositions exist.
