Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19926, here are decompositions:
- 7 + 19919 = 19926
- 13 + 19913 = 19926
- 37 + 19889 = 19926
- 59 + 19867 = 19926
- 73 + 19853 = 19926
- 83 + 19843 = 19926
- 107 + 19819 = 19926
- 113 + 19813 = 19926
Showing the first eight; more decompositions exist.
