Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72524, here are decompositions:

31 + 72493 = 72524
43 + 72481 = 72524
103 + 72421 = 72524
157 + 72367 = 72524
211 + 72313 = 72524
271 + 72253 = 72524
313 + 72211 = 72524
421 + 72103 = 72524

Showing the first eight; more decompositions exist.
