Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67940, here are decompositions:
- 7 + 67933 = 67940
- 13 + 67927 = 67940
- 73 + 67867 = 67940
- 97 + 67843 = 67940
- 139 + 67801 = 67940
- 151 + 67789 = 67940
- 157 + 67783 = 67940
- 163 + 67777 = 67940
Showing the first eight; more decompositions exist.
