Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87436, here are decompositions:

3 + 87433 = 87436
29 + 87407 = 87436
53 + 87383 = 87436
113 + 87323 = 87436
137 + 87299 = 87436
179 + 87257 = 87436
257 + 87179 = 87436
317 + 87119 = 87436

Showing the first eight; more decompositions exist.
