Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18370, here are decompositions:
- 3 + 18367 = 18370
- 17 + 18353 = 18370
- 29 + 18341 = 18370
- 41 + 18329 = 18370
- 59 + 18311 = 18370
- 83 + 18287 = 18370
- 101 + 18269 = 18370
- 113 + 18257 = 18370
Showing the first eight; more decompositions exist.
