Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22618, here are decompositions:
- 5 + 22613 = 22618
- 47 + 22571 = 22618
- 107 + 22511 = 22618
- 137 + 22481 = 22618
- 149 + 22469 = 22618
- 227 + 22391 = 22618
- 251 + 22367 = 22618
- 269 + 22349 = 22618
Showing the first eight; more decompositions exist.
