Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4518, here are decompositions:
- 5 + 4513 = 4518
- 11 + 4507 = 4518
- 37 + 4481 = 4518
- 61 + 4457 = 4518
- 67 + 4451 = 4518
- 71 + 4447 = 4518
- 97 + 4421 = 4518
- 109 + 4409 = 4518
Showing the first eight; more decompositions exist.
