Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8518, here are decompositions:
- 5 + 8513 = 8518
- 17 + 8501 = 8518
- 71 + 8447 = 8518
- 89 + 8429 = 8518
- 131 + 8387 = 8518
- 149 + 8369 = 8518
- 227 + 8291 = 8518
- 281 + 8237 = 8518
Showing the first eight; more decompositions exist.
