Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13930, here are decompositions:
- 17 + 13913 = 13930
- 23 + 13907 = 13930
- 29 + 13901 = 13930
- 47 + 13883 = 13930
- 53 + 13877 = 13930
- 71 + 13859 = 13930
- 89 + 13841 = 13930
- 101 + 13829 = 13930
Showing the first eight; more decompositions exist.
