Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71198, here are decompositions:
- 7 + 71191 = 71198
- 31 + 71167 = 71198
- 37 + 71161 = 71198
- 79 + 71119 = 71198
- 109 + 71089 = 71198
- 139 + 71059 = 71198
- 199 + 70999 = 71198
- 229 + 70969 = 71198
Showing the first eight; more decompositions exist.
