Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990798, here are decompositions:
- 31 + 990767 = 990798
- 37 + 990761 = 990798
- 79 + 990719 = 990798
- 167 + 990631 = 990798
- 199 + 990599 = 990798
- 239 + 990559 = 990798
- 251 + 990547 = 990798
- 269 + 990529 = 990798
Showing the first eight; more decompositions exist.
