Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989824, here are decompositions:
- 41 + 989783 = 989824
- 47 + 989777 = 989824
- 71 + 989753 = 989824
- 137 + 989687 = 989824
- 263 + 989561 = 989824
- 317 + 989507 = 989824
- 347 + 989477 = 989824
- 383 + 989441 = 989824
Showing the first eight; more decompositions exist.
