Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25972, here are decompositions:

3 + 25969 = 25972
29 + 25943 = 25972
41 + 25931 = 25972
53 + 25919 = 25972
59 + 25913 = 25972
83 + 25889 = 25972
131 + 25841 = 25972
173 + 25799 = 25972

Showing the first eight; more decompositions exist.
