Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987154, here are decompositions:

11 + 987143 = 987154
53 + 987101 = 987154
71 + 987083 = 987154
101 + 987053 = 987154
131 + 987023 = 987154
173 + 986981 = 987154
191 + 986963 = 987154
227 + 986927 = 987154

Showing the first eight; more decompositions exist.
