Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25676, here are decompositions:

3 + 25673 = 25676
19 + 25657 = 25676
37 + 25639 = 25676
43 + 25633 = 25676
67 + 25609 = 25676
73 + 25603 = 25676
97 + 25579 = 25676
139 + 25537 = 25676

Showing the first eight; more decompositions exist.
