Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18290, here are decompositions:
- 3 + 18287 = 18290
- 37 + 18253 = 18290
- 61 + 18229 = 18290
- 67 + 18223 = 18290
- 73 + 18217 = 18290
- 79 + 18211 = 18290
- 109 + 18181 = 18290
- 157 + 18133 = 18290
Showing the first eight; more decompositions exist.
