Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72454, here are decompositions:

23 + 72431 = 72454
71 + 72383 = 72454
101 + 72353 = 72454
113 + 72341 = 72454
167 + 72287 = 72454
227 + 72227 = 72454
233 + 72221 = 72454
281 + 72173 = 72454

Showing the first eight; more decompositions exist.
