Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987118, here are decompositions:

17 + 987101 = 987118
29 + 987089 = 987118
89 + 987029 = 987118
137 + 986981 = 987118
191 + 986927 = 987118
269 + 986849 = 987118
281 + 986837 = 987118
317 + 986801 = 987118

Showing the first eight; more decompositions exist.
