Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28862, here are decompositions:
- 3 + 28859 = 28862
- 19 + 28843 = 28862
- 73 + 28789 = 28862
- 103 + 28759 = 28862
- 109 + 28753 = 28862
- 139 + 28723 = 28862
- 151 + 28711 = 28862
- 193 + 28669 = 28862
Showing the first eight; more decompositions exist.
