Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20604, here are decompositions:
- 5 + 20599 = 20604
- 11 + 20593 = 20604
- 41 + 20563 = 20604
- 53 + 20551 = 20604
- 61 + 20543 = 20604
- 71 + 20533 = 20604
- 83 + 20521 = 20604
- 97 + 20507 = 20604
Showing the first eight; more decompositions exist.
