Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67978, here are decompositions:
- 11 + 67967 = 67978
- 17 + 67961 = 67978
- 47 + 67931 = 67978
- 149 + 67829 = 67978
- 227 + 67751 = 67978
- 269 + 67709 = 67978
- 347 + 67631 = 67978
- 359 + 67619 = 67978
Showing the first eight; more decompositions exist.
