Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72558, here are decompositions:

7 + 72551 = 72558
11 + 72547 = 72558
61 + 72497 = 72558
89 + 72469 = 72558
97 + 72461 = 72558
127 + 72431 = 72558
137 + 72421 = 72558
179 + 72379 = 72558

Showing the first eight; more decompositions exist.
