Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508728, here are decompositions:
- 19 + 508709 = 508728
- 67 + 508661 = 508728
- 107 + 508621 = 508728
- 109 + 508619 = 508728
- 149 + 508579 = 508728
- 151 + 508577 = 508728
- 179 + 508549 = 508728
- 197 + 508531 = 508728
Showing the first eight; more decompositions exist.
