Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3926, here are decompositions:
- 3 + 3923 = 3926
- 7 + 3919 = 3926
- 19 + 3907 = 3926
- 37 + 3889 = 3926
- 73 + 3853 = 3926
- 79 + 3847 = 3926
- 103 + 3823 = 3926
- 157 + 3769 = 3926
Showing the first eight; more decompositions exist.
