Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72588, here are decompositions:

11 + 72577 = 72588
29 + 72559 = 72588
37 + 72551 = 72588
41 + 72547 = 72588
107 + 72481 = 72588
127 + 72461 = 72588
157 + 72431 = 72588
167 + 72421 = 72588

Showing the first eight; more decompositions exist.
