Goldbach decomposition

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.
