Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748816, here are decompositions:
- 5 + 8748811 = 8748816
- 29 + 8748787 = 8748816
- 73 + 8748743 = 8748816
- 103 + 8748713 = 8748816
- 107 + 8748709 = 8748816
- 163 + 8748653 = 8748816
- 173 + 8748643 = 8748816
- 227 + 8748589 = 8748816
Showing the first eight; more decompositions exist.
