Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28604, here are decompositions:

7 + 28597 = 28604
13 + 28591 = 28604
31 + 28573 = 28604
67 + 28537 = 28604
127 + 28477 = 28604
157 + 28447 = 28604
193 + 28411 = 28604
211 + 28393 = 28604

Showing the first eight; more decompositions exist.
