Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987376, here are decompositions:

23 + 987353 = 987376
83 + 987293 = 987376
149 + 987227 = 987376
167 + 987209 = 987376
233 + 987143 = 987376
293 + 987083 = 987376
347 + 987029 = 987376
353 + 987023 = 987376

Showing the first eight; more decompositions exist.
