Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73840, here are decompositions:
- 17 + 73823 = 73840
- 83 + 73757 = 73840
- 89 + 73751 = 73840
- 113 + 73727 = 73840
- 131 + 73709 = 73840
- 167 + 73673 = 73840
- 197 + 73643 = 73840
- 227 + 73613 = 73840
Showing the first eight; more decompositions exist.
