Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25700, here are decompositions:

7 + 25693 = 25700
43 + 25657 = 25700
61 + 25639 = 25700
67 + 25633 = 25700
79 + 25621 = 25700
97 + 25603 = 25700
139 + 25561 = 25700
163 + 25537 = 25700

Showing the first eight; more decompositions exist.
