Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3884, here are decompositions:
- 3 + 3881 = 3884
- 7 + 3877 = 3884
- 31 + 3853 = 3884
- 37 + 3847 = 3884
- 61 + 3823 = 3884
- 151 + 3733 = 3884
- 157 + 3727 = 3884
- 193 + 3691 = 3884
Showing the first eight; more decompositions exist.
