Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987106, here are decompositions:

5 + 987101 = 987106
17 + 987089 = 987106
23 + 987083 = 987106
53 + 987053 = 987106
83 + 987023 = 987106
173 + 986933 = 987106
179 + 986927 = 987106
257 + 986849 = 987106

Showing the first eight; more decompositions exist.
