Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987436, here are decompositions:

3 + 987433 = 987436
53 + 987383 = 987436
83 + 987353 = 987436
137 + 987299 = 987436
227 + 987209 = 987436
293 + 987143 = 987436
347 + 987089 = 987436
353 + 987083 = 987436

Showing the first eight; more decompositions exist.
