Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748684, here are decompositions:
- 11 + 8748673 = 8748684
- 31 + 8748653 = 8748684
- 37 + 8748647 = 8748684
- 41 + 8748643 = 8748684
- 83 + 8748601 = 8748684
- 97 + 8748587 = 8748684
- 101 + 8748583 = 8748684
- 103 + 8748581 = 8748684
Showing the first eight; more decompositions exist.
