Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 67880, here are decompositions:
- 13 + 67867 = 67880
- 37 + 67843 = 67880
- 61 + 67819 = 67880
- 73 + 67807 = 67880
- 79 + 67801 = 67880
- 97 + 67783 = 67880
- 103 + 67777 = 67880
- 139 + 67741 = 67880
Showing the first eight; more decompositions exist.
