Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12860, here are decompositions:
- 7 + 12853 = 12860
- 19 + 12841 = 12860
- 31 + 12829 = 12860
- 37 + 12823 = 12860
- 61 + 12799 = 12860
- 79 + 12781 = 12860
- 97 + 12763 = 12860
- 103 + 12757 = 12860
Showing the first eight; more decompositions exist.
