Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99880, here are decompositions:
- 3 + 99877 = 99880
- 41 + 99839 = 99880
- 47 + 99833 = 99880
- 71 + 99809 = 99880
- 113 + 99767 = 99880
- 167 + 99713 = 99880
- 173 + 99707 = 99880
- 191 + 99689 = 99880
Showing the first eight; more decompositions exist.
