Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88988, here are decompositions:
- 19 + 88969 = 88988
- 37 + 88951 = 88988
- 127 + 88861 = 88988
- 181 + 88807 = 88988
- 199 + 88789 = 88988
- 241 + 88747 = 88988
- 307 + 88681 = 88988
- 331 + 88657 = 88988
Showing the first eight; more decompositions exist.
