Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178848, here are decompositions:
- 17 + 178831 = 178848
- 29 + 178819 = 178848
- 31 + 178817 = 178848
- 41 + 178807 = 178848
- 67 + 178781 = 178848
- 151 + 178697 = 178848
- 157 + 178691 = 178848
- 167 + 178681 = 178848
Showing the first eight; more decompositions exist.
