Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67518, here are decompositions:
- 7 + 67511 = 67518
- 19 + 67499 = 67518
- 29 + 67489 = 67518
- 37 + 67481 = 67518
- 41 + 67477 = 67518
- 71 + 67447 = 67518
- 89 + 67429 = 67518
- 97 + 67421 = 67518
Showing the first eight; more decompositions exist.
