Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25758, here are decompositions:

11 + 25747 = 25758
17 + 25741 = 25758
41 + 25717 = 25758
79 + 25679 = 25758
101 + 25657 = 25758
137 + 25621 = 25758
149 + 25609 = 25758
157 + 25601 = 25758

Showing the first eight; more decompositions exist.
