Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13992, here are decompositions:
- 29 + 13963 = 13992
- 59 + 13933 = 13992
- 61 + 13931 = 13992
- 71 + 13921 = 13992
- 79 + 13913 = 13992
- 89 + 13903 = 13992
- 109 + 13883 = 13992
- 113 + 13879 = 13992
Showing the first eight; more decompositions exist.
