Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66738, here are decompositions:
- 5 + 66733 = 66738
- 17 + 66721 = 66738
- 37 + 66701 = 66738
- 41 + 66697 = 66738
- 109 + 66629 = 66738
- 137 + 66601 = 66738
- 151 + 66587 = 66738
- 167 + 66571 = 66738
Showing the first eight; more decompositions exist.
