Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67980, here are decompositions:
- 13 + 67967 = 67980
- 19 + 67961 = 67980
- 23 + 67957 = 67980
- 37 + 67943 = 67980
- 41 + 67939 = 67980
- 47 + 67933 = 67980
- 53 + 67927 = 67980
- 79 + 67901 = 67980
Showing the first eight; more decompositions exist.
