Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19284, here are decompositions:
- 11 + 19273 = 19284
- 17 + 19267 = 19284
- 47 + 19237 = 19284
- 53 + 19231 = 19284
- 71 + 19213 = 19284
- 73 + 19211 = 19284
- 101 + 19183 = 19284
- 103 + 19181 = 19284
Showing the first eight; more decompositions exist.
