Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989788, here are decompositions:
- 5 + 989783 = 989788
- 11 + 989777 = 989788
- 101 + 989687 = 989788
- 227 + 989561 = 989788
- 281 + 989507 = 989788
- 311 + 989477 = 989788
- 347 + 989441 = 989788
- 461 + 989327 = 989788
Showing the first eight; more decompositions exist.
