Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66648, here are decompositions:
- 5 + 66643 = 66648
- 19 + 66629 = 66648
- 31 + 66617 = 66648
- 47 + 66601 = 66648
- 61 + 66587 = 66648
- 79 + 66569 = 66648
- 107 + 66541 = 66648
- 139 + 66509 = 66648
Showing the first eight; more decompositions exist.
