Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87524, here are decompositions:

7 + 87517 = 87524
13 + 87511 = 87524
43 + 87481 = 87524
97 + 87427 = 87524
103 + 87421 = 87524
211 + 87313 = 87524
271 + 87253 = 87524
313 + 87211 = 87524

Showing the first eight; more decompositions exist.
