Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3954, here are decompositions:
- 7 + 3947 = 3954
- 11 + 3943 = 3954
- 23 + 3931 = 3954
- 31 + 3923 = 3954
- 37 + 3917 = 3954
- 43 + 3911 = 3954
- 47 + 3907 = 3954
- 73 + 3881 = 3954
Showing the first eight; more decompositions exist.
