Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19622, here are decompositions:

13 + 19609 = 19622
19 + 19603 = 19622
79 + 19543 = 19622
139 + 19483 = 19622
151 + 19471 = 19622
181 + 19441 = 19622
193 + 19429 = 19622
199 + 19423 = 19622

Showing the first eight; more decompositions exist.
