Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25518, here are decompositions:

47 + 25471 = 25518
61 + 25457 = 25518
71 + 25447 = 25518
79 + 25439 = 25518
107 + 25411 = 25518
109 + 25409 = 25518
127 + 25391 = 25518
151 + 25367 = 25518

Showing the first eight; more decompositions exist.
