Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67540, here are decompositions:
- 3 + 67537 = 67540
- 17 + 67523 = 67540
- 29 + 67511 = 67540
- 41 + 67499 = 67540
- 47 + 67493 = 67540
- 59 + 67481 = 67540
- 107 + 67433 = 67540
- 113 + 67427 = 67540
Showing the first eight; more decompositions exist.
