Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66744, here are decompositions:
- 5 + 66739 = 66744
- 11 + 66733 = 66744
- 23 + 66721 = 66744
- 31 + 66713 = 66744
- 43 + 66701 = 66744
- 47 + 66697 = 66744
- 61 + 66683 = 66744
- 101 + 66643 = 66744
Showing the first eight; more decompositions exist.
