Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42372, here are decompositions:

13 + 42359 = 42372
23 + 42349 = 42372
41 + 42331 = 42372
73 + 42299 = 42372
79 + 42293 = 42372
89 + 42283 = 42372
149 + 42223 = 42372
151 + 42221 = 42372

Showing the first eight; more decompositions exist.
