Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71148, here are decompositions:
- 5 + 71143 = 71148
- 19 + 71129 = 71148
- 29 + 71119 = 71148
- 59 + 71089 = 71148
- 67 + 71081 = 71148
- 79 + 71069 = 71148
- 89 + 71059 = 71148
- 109 + 71039 = 71148
Showing the first eight; more decompositions exist.
