Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42202, here are decompositions:

5 + 42197 = 42202
23 + 42179 = 42202
71 + 42131 = 42202
101 + 42101 = 42202
113 + 42089 = 42202
131 + 42071 = 42202
179 + 42023 = 42202
233 + 41969 = 42202

Showing the first eight; more decompositions exist.
