Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66774, here are decompositions:
- 11 + 66763 = 66774
- 23 + 66751 = 66774
- 41 + 66733 = 66774
- 53 + 66721 = 66774
- 61 + 66713 = 66774
- 73 + 66701 = 66774
- 131 + 66643 = 66774
- 157 + 66617 = 66774
Showing the first eight; more decompositions exist.
