Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66654, here are decompositions:
- 11 + 66643 = 66654
- 37 + 66617 = 66654
- 53 + 66601 = 66654
- 61 + 66593 = 66654
- 67 + 66587 = 66654
- 83 + 66571 = 66654
- 101 + 66553 = 66654
- 113 + 66541 = 66654
Showing the first eight; more decompositions exist.
