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.
