Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12924, here are decompositions:
- 5 + 12919 = 12924
- 7 + 12917 = 12924
- 13 + 12911 = 12924
- 17 + 12907 = 12924
- 31 + 12893 = 12924
- 71 + 12853 = 12924
- 83 + 12841 = 12924
- 101 + 12823 = 12924
Showing the first eight; more decompositions exist.
