Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42430, here are decompositions:

23 + 42407 = 42430
71 + 42359 = 42430
107 + 42323 = 42430
131 + 42299 = 42430
137 + 42293 = 42430
149 + 42281 = 42430
173 + 42257 = 42430
191 + 42239 = 42430

Showing the first eight; more decompositions exist.
