Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49806, here are decompositions:
- 5 + 49801 = 49806
- 17 + 49789 = 49806
- 19 + 49787 = 49806
- 23 + 49783 = 49806
- 59 + 49747 = 49806
- 67 + 49739 = 49806
- 79 + 49727 = 49806
- 109 + 49697 = 49806
Showing the first eight; more decompositions exist.
