Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12930, here are decompositions:
- 7 + 12923 = 12930
- 11 + 12919 = 12930
- 13 + 12917 = 12930
- 19 + 12911 = 12930
- 23 + 12907 = 12930
- 31 + 12899 = 12930
- 37 + 12893 = 12930
- 41 + 12889 = 12930
Showing the first eight; more decompositions exist.
