Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71312, here are decompositions:
- 19 + 71293 = 71312
- 79 + 71233 = 71312
- 103 + 71209 = 71312
- 151 + 71161 = 71312
- 193 + 71119 = 71312
- 223 + 71089 = 71312
- 313 + 70999 = 71312
- 331 + 70981 = 71312
Showing the first eight; more decompositions exist.
