Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12908, here are decompositions:
- 19 + 12889 = 12908
- 67 + 12841 = 12908
- 79 + 12829 = 12908
- 109 + 12799 = 12908
- 127 + 12781 = 12908
- 151 + 12757 = 12908
- 211 + 12697 = 12908
- 271 + 12637 = 12908
Showing the first eight; more decompositions exist.
