Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71912, here are decompositions:
- 3 + 71909 = 71912
- 13 + 71899 = 71912
- 31 + 71881 = 71912
- 103 + 71809 = 71912
- 151 + 71761 = 71912
- 193 + 71719 = 71912
- 199 + 71713 = 71912
- 241 + 71671 = 71912
Showing the first eight; more decompositions exist.
