Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22002, here are decompositions:

5 + 21997 = 22002
11 + 21991 = 22002
41 + 21961 = 22002
59 + 21943 = 22002
73 + 21929 = 22002
109 + 21893 = 22002
131 + 21871 = 22002
139 + 21863 = 22002

Showing the first eight; more decompositions exist.
