Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16254, here are decompositions:
- 5 + 16249 = 16254
- 23 + 16231 = 16254
- 31 + 16223 = 16254
- 37 + 16217 = 16254
- 61 + 16193 = 16254
- 67 + 16187 = 16254
- 71 + 16183 = 16254
- 113 + 16141 = 16254
Showing the first eight; more decompositions exist.
