Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13938, here are decompositions:
- 5 + 13933 = 13938
- 7 + 13931 = 13938
- 17 + 13921 = 13938
- 31 + 13907 = 13938
- 37 + 13901 = 13938
- 59 + 13879 = 13938
- 61 + 13877 = 13938
- 79 + 13859 = 13938
Showing the first eight; more decompositions exist.
