Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 167880, here are decompositions:
- 7 + 167873 = 167880
- 17 + 167863 = 167880
- 19 + 167861 = 167880
- 71 + 167809 = 167880
- 79 + 167801 = 167880
- 101 + 167779 = 167880
- 103 + 167777 = 167880
- 109 + 167771 = 167880
Showing the first eight; more decompositions exist.
