Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42222, here are decompositions:

13 + 42209 = 42222
29 + 42193 = 42222
41 + 42181 = 42222
43 + 42179 = 42222
53 + 42169 = 42222
83 + 42139 = 42222
139 + 42083 = 42222
149 + 42073 = 42222

Showing the first eight; more decompositions exist.
