Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66844, here are decompositions:
- 3 + 66841 = 66844
- 23 + 66821 = 66844
- 47 + 66797 = 66844
- 53 + 66791 = 66844
- 131 + 66713 = 66844
- 191 + 66653 = 66844
- 227 + 66617 = 66844
- 251 + 66593 = 66844
Showing the first eight; more decompositions exist.
