Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2844, here are decompositions:
- 7 + 2837 = 2844
- 11 + 2833 = 2844
- 41 + 2803 = 2844
- 43 + 2801 = 2844
- 47 + 2797 = 2844
- 53 + 2791 = 2844
- 67 + 2777 = 2844
- 103 + 2741 = 2844
Showing the first eight; more decompositions exist.
