Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25984, here are decompositions:

3 + 25981 = 25984
41 + 25943 = 25984
53 + 25931 = 25984
71 + 25913 = 25984
137 + 25847 = 25984
191 + 25793 = 25984
251 + 25733 = 25984
281 + 25703 = 25984

Showing the first eight; more decompositions exist.
