Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990792, here are decompositions:
- 31 + 990761 = 990792
- 59 + 990733 = 990792
- 73 + 990719 = 990792
- 149 + 990643 = 990792
- 193 + 990599 = 990792
- 199 + 990593 = 990792
- 233 + 990559 = 990792
- 263 + 990529 = 990792
Showing the first eight; more decompositions exist.
