Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6518, here are decompositions:
- 37 + 6481 = 6518
- 67 + 6451 = 6518
- 97 + 6421 = 6518
- 139 + 6379 = 6518
- 151 + 6367 = 6518
- 157 + 6361 = 6518
- 181 + 6337 = 6518
- 241 + 6277 = 6518
Showing the first eight; more decompositions exist.
