Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28622, here are decompositions:

3 + 28619 = 28622
19 + 28603 = 28622
31 + 28591 = 28622
43 + 28579 = 28622
73 + 28549 = 28622
109 + 28513 = 28622
193 + 28429 = 28622
211 + 28411 = 28622

Showing the first eight; more decompositions exist.
