Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28194, here are decompositions:
- 11 + 28183 = 28194
- 13 + 28181 = 28194
- 31 + 28163 = 28194
- 43 + 28151 = 28194
- 71 + 28123 = 28194
- 83 + 28111 = 28194
- 97 + 28097 = 28194
- 107 + 28087 = 28194
Showing the first eight; more decompositions exist.
