Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42370, here are decompositions:

11 + 42359 = 42370
47 + 42323 = 42370
71 + 42299 = 42370
89 + 42281 = 42370
113 + 42257 = 42370
131 + 42239 = 42370
149 + 42221 = 42370
173 + 42197 = 42370

Showing the first eight; more decompositions exist.
