Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987274, here are decompositions:

23 + 987251 = 987274
47 + 987227 = 987274
83 + 987191 = 987274
131 + 987143 = 987274
173 + 987101 = 987274
191 + 987083 = 987274
251 + 987023 = 987274
293 + 986981 = 987274

Showing the first eight; more decompositions exist.
