Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987202, here are decompositions:

3 + 987199 = 987202
11 + 987191 = 987202
59 + 987143 = 987202
101 + 987101 = 987202
113 + 987089 = 987202
149 + 987053 = 987202
173 + 987029 = 987202
179 + 987023 = 987202

Showing the first eight; more decompositions exist.
