Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22530, here are decompositions:

19 + 22511 = 22530
29 + 22501 = 22530
47 + 22483 = 22530
61 + 22469 = 22530
83 + 22447 = 22530
89 + 22441 = 22530
97 + 22433 = 22530
139 + 22391 = 22530

Showing the first eight; more decompositions exist.
