Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71286, here are decompositions:
- 23 + 71263 = 71286
- 29 + 71257 = 71286
- 37 + 71249 = 71286
- 53 + 71233 = 71286
- 139 + 71147 = 71286
- 157 + 71129 = 71286
- 167 + 71119 = 71286
- 197 + 71089 = 71286
Showing the first eight; more decompositions exist.
