Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7680, here are decompositions:
- 7 + 7673 = 7680
- 11 + 7669 = 7680
- 31 + 7649 = 7680
- 37 + 7643 = 7680
- 41 + 7639 = 7680
- 59 + 7621 = 7680
- 73 + 7607 = 7680
- 89 + 7591 = 7680
Showing the first eight; more decompositions exist.
