Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28846, here are decompositions:
- 3 + 28843 = 28846
- 29 + 28817 = 28846
- 53 + 28793 = 28846
- 149 + 28697 = 28846
- 197 + 28649 = 28846
- 227 + 28619 = 28846
- 239 + 28607 = 28846
- 347 + 28499 = 28846
Showing the first eight; more decompositions exist.
