Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71944, here are decompositions:
- 3 + 71941 = 71944
- 11 + 71933 = 71944
- 83 + 71861 = 71944
- 101 + 71843 = 71944
- 107 + 71837 = 71944
- 137 + 71807 = 71944
- 167 + 71777 = 71944
- 233 + 71711 = 71944
Showing the first eight; more decompositions exist.
