Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5518, here are decompositions:
- 11 + 5507 = 5518
- 17 + 5501 = 5518
- 41 + 5477 = 5518
- 47 + 5471 = 5518
- 101 + 5417 = 5518
- 131 + 5387 = 5518
- 137 + 5381 = 5518
- 167 + 5351 = 5518
Showing the first eight; more decompositions exist.
