Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 53178, here are decompositions:
- 5 + 53173 = 53178
- 7 + 53171 = 53178
- 17 + 53161 = 53178
- 29 + 53149 = 53178
- 31 + 53147 = 53178
- 61 + 53117 = 53178
- 89 + 53089 = 53178
- 101 + 53077 = 53178
Showing the first eight; more decompositions exist.
