Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49800, here are decompositions:
- 11 + 49789 = 49800
- 13 + 49787 = 49800
- 17 + 49783 = 49800
- 43 + 49757 = 49800
- 53 + 49747 = 49800
- 59 + 49741 = 49800
- 61 + 49739 = 49800
- 73 + 49727 = 49800
Showing the first eight; more decompositions exist.
