Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99988, here are decompositions:
- 17 + 99971 = 99988
- 59 + 99929 = 99988
- 107 + 99881 = 99988
- 149 + 99839 = 99988
- 179 + 99809 = 99988
- 227 + 99761 = 99988
- 269 + 99719 = 99988
- 281 + 99707 = 99988
Showing the first eight; more decompositions exist.
