Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72574, here are decompositions:

23 + 72551 = 72574
41 + 72533 = 72574
71 + 72503 = 72574
107 + 72467 = 72574
113 + 72461 = 72574
191 + 72383 = 72574
233 + 72341 = 72574
347 + 72227 = 72574

Showing the first eight; more decompositions exist.
