Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10918, here are decompositions:
- 29 + 10889 = 10918
- 59 + 10859 = 10918
- 71 + 10847 = 10918
- 137 + 10781 = 10918
- 179 + 10739 = 10918
- 227 + 10691 = 10918
- 251 + 10667 = 10918
- 311 + 10607 = 10918
Showing the first eight; more decompositions exist.
