Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72502, here are decompositions:

5 + 72497 = 72502
41 + 72461 = 72502
71 + 72431 = 72502
149 + 72353 = 72502
233 + 72269 = 72502
251 + 72251 = 72502
281 + 72221 = 72502
401 + 72101 = 72502

Showing the first eight; more decompositions exist.
