Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990804, here are decompositions:
- 5 + 990799 = 990804
- 7 + 990797 = 990804
- 37 + 990767 = 990804
- 43 + 990761 = 990804
- 71 + 990733 = 990804
- 97 + 990707 = 990804
- 131 + 990673 = 990804
- 167 + 990637 = 990804
Showing the first eight; more decompositions exist.
