Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42200, here are decompositions:

3 + 42197 = 42200
7 + 42193 = 42200
13 + 42187 = 42200
19 + 42181 = 42200
31 + 42169 = 42200
43 + 42157 = 42200
61 + 42139 = 42200
127 + 42073 = 42200

Showing the first eight; more decompositions exist.
