Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12894, here are decompositions:
- 5 + 12889 = 12894
- 41 + 12853 = 12894
- 53 + 12841 = 12894
- 71 + 12823 = 12894
- 73 + 12821 = 12894
- 103 + 12791 = 12894
- 113 + 12781 = 12894
- 131 + 12763 = 12894
Showing the first eight; more decompositions exist.
