Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72532, here are decompositions:

29 + 72503 = 72532
71 + 72461 = 72532
101 + 72431 = 72532
149 + 72383 = 72532
179 + 72353 = 72532
191 + 72341 = 72532
263 + 72269 = 72532
281 + 72251 = 72532

Showing the first eight; more decompositions exist.
