Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42472, here are decompositions:

5 + 42467 = 42472
11 + 42461 = 42472
29 + 42443 = 42472
113 + 42359 = 42472
149 + 42323 = 42472
173 + 42299 = 42472
179 + 42293 = 42472
191 + 42281 = 42472

Showing the first eight; more decompositions exist.
