Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43518, here are decompositions:
- 19 + 43499 = 43518
- 31 + 43487 = 43518
- 37 + 43481 = 43518
- 61 + 43457 = 43518
- 67 + 43451 = 43518
- 107 + 43411 = 43518
- 127 + 43391 = 43518
- 197 + 43321 = 43518
Showing the first eight; more decompositions exist.
