Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71172, here are decompositions:
- 5 + 71167 = 71172
- 11 + 71161 = 71172
- 19 + 71153 = 71172
- 29 + 71143 = 71172
- 43 + 71129 = 71172
- 53 + 71119 = 71172
- 83 + 71089 = 71172
- 103 + 71069 = 71172
Showing the first eight; more decompositions exist.
