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.
