Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25604, here are decompositions:

3 + 25601 = 25604
43 + 25561 = 25604
67 + 25537 = 25604
151 + 25453 = 25604
157 + 25447 = 25604
181 + 25423 = 25604
193 + 25411 = 25604
283 + 25321 = 25604

Showing the first eight; more decompositions exist.
