Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178844, here are decompositions:
- 13 + 178831 = 178844
- 31 + 178813 = 178844
- 37 + 178807 = 178844
- 151 + 178693 = 178844
- 163 + 178681 = 178844
- 223 + 178621 = 178844
- 241 + 178603 = 178844
- 277 + 178567 = 178844
Showing the first eight; more decompositions exist.
