Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22840, here are decompositions:
- 23 + 22817 = 22840
- 29 + 22811 = 22840
- 53 + 22787 = 22840
- 71 + 22769 = 22840
- 89 + 22751 = 22840
- 101 + 22739 = 22840
- 113 + 22727 = 22840
- 131 + 22709 = 22840
Showing the first eight; more decompositions exist.
