Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8524, here are decompositions:

3 + 8521 = 8524
11 + 8513 = 8524
23 + 8501 = 8524
101 + 8423 = 8524
137 + 8387 = 8524
227 + 8297 = 8524
233 + 8291 = 8524
251 + 8273 = 8524

Showing the first eight; more decompositions exist.
