Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66940, here are decompositions:
- 17 + 66923 = 66940
- 89 + 66851 = 66940
- 131 + 66809 = 66940
- 149 + 66791 = 66940
- 191 + 66749 = 66940
- 227 + 66713 = 66940
- 239 + 66701 = 66940
- 257 + 66683 = 66940
Showing the first eight; more decompositions exist.
