Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2826, here are decompositions:
- 7 + 2819 = 2826
- 23 + 2803 = 2826
- 29 + 2797 = 2826
- 37 + 2789 = 2826
- 59 + 2767 = 2826
- 73 + 2753 = 2826
- 97 + 2729 = 2826
- 107 + 2719 = 2826
Showing the first eight; more decompositions exist.
