Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74664, here are decompositions:
- 11 + 74653 = 74664
- 41 + 74623 = 74664
- 53 + 74611 = 74664
- 67 + 74597 = 74664
- 97 + 74567 = 74664
- 103 + 74561 = 74664
- 113 + 74551 = 74664
- 137 + 74527 = 74664
Showing the first eight; more decompositions exist.
