Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22290, here are decompositions:
- 7 + 22283 = 22290
- 11 + 22279 = 22290
- 13 + 22277 = 22290
- 17 + 22273 = 22290
- 19 + 22271 = 22290
- 31 + 22259 = 22290
- 43 + 22247 = 22290
- 61 + 22229 = 22290
Showing the first eight; more decompositions exist.
