Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989722, here are decompositions:
- 3 + 989719 = 989722
- 59 + 989663 = 989722
- 281 + 989441 = 989722
- 311 + 989411 = 989722
- 401 + 989321 = 989722
- 443 + 989279 = 989722
- 491 + 989231 = 989722
- 599 + 989123 = 989722
Showing the first eight; more decompositions exist.
