Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7198, here are decompositions:
- 5 + 7193 = 7198
- 11 + 7187 = 7198
- 47 + 7151 = 7198
- 71 + 7127 = 7198
- 89 + 7109 = 7198
- 179 + 7019 = 7198
- 197 + 7001 = 7198
- 227 + 6971 = 7198
Showing the first eight; more decompositions exist.
