Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998200, here are decompositions:
- 3 + 998197 = 998200
- 53 + 998147 = 998200
- 83 + 998117 = 998200
- 89 + 998111 = 998200
- 131 + 998069 = 998200
- 173 + 998027 = 998200
- 191 + 998009 = 998200
- 227 + 997973 = 998200
Showing the first eight; more decompositions exist.
