Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71954, here are decompositions:
- 7 + 71947 = 71954
- 13 + 71941 = 71954
- 37 + 71917 = 71954
- 67 + 71887 = 71954
- 73 + 71881 = 71954
- 193 + 71761 = 71954
- 241 + 71713 = 71954
- 283 + 71671 = 71954
Showing the first eight; more decompositions exist.
