Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22456, here are decompositions:

3 + 22453 = 22456
23 + 22433 = 22456
47 + 22409 = 22456
59 + 22397 = 22456
89 + 22367 = 22456
107 + 22349 = 22456
113 + 22343 = 22456
149 + 22307 = 22456

Showing the first eight; more decompositions exist.
