Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19974, here are decompositions:
- 11 + 19963 = 19974
- 13 + 19961 = 19974
- 37 + 19937 = 19974
- 47 + 19927 = 19974
- 61 + 19913 = 19974
- 83 + 19891 = 19974
- 107 + 19867 = 19974
- 113 + 19861 = 19974
Showing the first eight; more decompositions exist.
