Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72528, here are decompositions:

31 + 72497 = 72528
47 + 72481 = 72528
59 + 72469 = 72528
61 + 72467 = 72528
67 + 72461 = 72528
97 + 72431 = 72528
107 + 72421 = 72528
149 + 72379 = 72528

Showing the first eight; more decompositions exist.
