Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71166, here are decompositions:
- 5 + 71161 = 71166
- 13 + 71153 = 71166
- 19 + 71147 = 71166
- 23 + 71143 = 71166
- 37 + 71129 = 71166
- 47 + 71119 = 71166
- 97 + 71069 = 71166
- 107 + 71059 = 71166
Showing the first eight; more decompositions exist.
