Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51678, here are decompositions:
- 5 + 51673 = 51678
- 19 + 51659 = 51678
- 31 + 51647 = 51678
- 41 + 51637 = 51678
- 47 + 51631 = 51678
- 71 + 51607 = 51678
- 79 + 51599 = 51678
- 97 + 51581 = 51678
Showing the first eight; more decompositions exist.
