Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18276, here are decompositions:
- 7 + 18269 = 18276
- 19 + 18257 = 18276
- 23 + 18253 = 18276
- 43 + 18233 = 18276
- 47 + 18229 = 18276
- 53 + 18223 = 18276
- 59 + 18217 = 18276
- 107 + 18169 = 18276
Showing the first eight; more decompositions exist.
