Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71192, here are decompositions:
- 31 + 71161 = 71192
- 73 + 71119 = 71192
- 103 + 71089 = 71192
- 181 + 71011 = 71192
- 193 + 70999 = 71192
- 211 + 70981 = 71192
- 223 + 70969 = 71192
- 241 + 70951 = 71192
Showing the first eight; more decompositions exist.
