Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71156, here are decompositions:
- 3 + 71153 = 71156
- 13 + 71143 = 71156
- 37 + 71119 = 71156
- 67 + 71089 = 71156
- 97 + 71059 = 71156
- 157 + 70999 = 71156
- 199 + 70957 = 71156
- 277 + 70879 = 71156
Showing the first eight; more decompositions exist.
