Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28852, here are decompositions:
- 59 + 28793 = 28852
- 101 + 28751 = 28852
- 149 + 28703 = 28852
- 191 + 28661 = 28852
- 233 + 28619 = 28852
- 281 + 28571 = 28852
- 293 + 28559 = 28852
- 311 + 28541 = 28852
Showing the first eight; more decompositions exist.
