Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72474, here are decompositions:

5 + 72469 = 72474
7 + 72467 = 72474
13 + 72461 = 72474
43 + 72431 = 72474
53 + 72421 = 72474
107 + 72367 = 72474
137 + 72337 = 72474
167 + 72307 = 72474

Showing the first eight; more decompositions exist.
