Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18260, here are decompositions:
- 3 + 18257 = 18260
- 7 + 18253 = 18260
- 31 + 18229 = 18260
- 37 + 18223 = 18260
- 43 + 18217 = 18260
- 61 + 18199 = 18260
- 79 + 18181 = 18260
- 127 + 18133 = 18260
Showing the first eight; more decompositions exist.
