Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82604, here are decompositions:
- 3 + 82601 = 82604
- 13 + 82591 = 82604
- 37 + 82567 = 82604
- 43 + 82561 = 82604
- 73 + 82531 = 82604
- 97 + 82507 = 82604
- 211 + 82393 = 82604
- 337 + 82267 = 82604
Showing the first eight; more decompositions exist.
