Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13950, here are decompositions:
- 17 + 13933 = 13950
- 19 + 13931 = 13950
- 29 + 13921 = 13950
- 37 + 13913 = 13950
- 43 + 13907 = 13950
- 47 + 13903 = 13950
- 67 + 13883 = 13950
- 71 + 13879 = 13950
Showing the first eight; more decompositions exist.
