Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42206, here are decompositions:

13 + 42193 = 42206
19 + 42187 = 42206
37 + 42169 = 42206
67 + 42139 = 42206
163 + 42043 = 42206
193 + 42013 = 42206
223 + 41983 = 42206
313 + 41893 = 42206

Showing the first eight; more decompositions exist.
