Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61198, here are decompositions:
- 29 + 61169 = 61198
- 47 + 61151 = 61198
- 107 + 61091 = 61198
- 167 + 61031 = 61198
- 191 + 61007 = 61198
- 197 + 61001 = 61198
- 281 + 60917 = 61198
- 311 + 60887 = 61198
Showing the first eight; more decompositions exist.
