Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22390, here are decompositions:
- 23 + 22367 = 22390
- 41 + 22349 = 22390
- 47 + 22343 = 22390
- 83 + 22307 = 22390
- 107 + 22283 = 22390
- 113 + 22277 = 22390
- 131 + 22259 = 22390
- 197 + 22193 = 22390
Showing the first eight; more decompositions exist.
