Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71916, here are decompositions:
- 7 + 71909 = 71916
- 17 + 71899 = 71916
- 29 + 71887 = 71916
- 37 + 71879 = 71916
- 67 + 71849 = 71916
- 73 + 71843 = 71916
- 79 + 71837 = 71916
- 107 + 71809 = 71916
Showing the first eight; more decompositions exist.
