Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989908, here are decompositions:
- 71 + 989837 = 989908
- 131 + 989777 = 989908
- 347 + 989561 = 989908
- 401 + 989507 = 989908
- 431 + 989477 = 989908
- 467 + 989441 = 989908
- 587 + 989321 = 989908
- 599 + 989309 = 989908
Showing the first eight; more decompositions exist.
