Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25890, here are decompositions:

17 + 25873 = 25890
23 + 25867 = 25890
41 + 25849 = 25890
43 + 25847 = 25890
71 + 25819 = 25890
89 + 25801 = 25890
97 + 25793 = 25890
127 + 25763 = 25890

Showing the first eight; more decompositions exist.
