Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71162, here are decompositions:
- 19 + 71143 = 71162
- 43 + 71119 = 71162
- 73 + 71089 = 71162
- 103 + 71059 = 71162
- 139 + 71023 = 71162
- 151 + 71011 = 71162
- 163 + 70999 = 71162
- 181 + 70981 = 71162
Showing the first eight; more decompositions exist.
