Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604, here are decompositions:

5 + 8599 = 8604
7 + 8597 = 8604
23 + 8581 = 8604
31 + 8573 = 8604
41 + 8563 = 8604
61 + 8543 = 8604
67 + 8537 = 8604
83 + 8521 = 8604

Showing the first eight; more decompositions exist.
