Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2604, here are decompositions:
- 11 + 2593 = 2604
- 13 + 2591 = 2604
- 47 + 2557 = 2604
- 53 + 2551 = 2604
- 61 + 2543 = 2604
- 73 + 2531 = 2604
- 83 + 2521 = 2604
- 101 + 2503 = 2604
Showing the first eight; more decompositions exist.
