Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13124, here are decompositions:
- 3 + 13121 = 13124
- 31 + 13093 = 13124
- 61 + 13063 = 13124
- 151 + 12973 = 13124
- 157 + 12967 = 13124
- 271 + 12853 = 13124
- 283 + 12841 = 13124
- 367 + 12757 = 13124
Showing the first eight; more decompositions exist.
