Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42418, here are decompositions:

11 + 42407 = 42418
59 + 42359 = 42418
137 + 42281 = 42418
179 + 42239 = 42418
191 + 42227 = 42418
197 + 42221 = 42418
239 + 42179 = 42418
317 + 42101 = 42418

Showing the first eight; more decompositions exist.
