Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49818, here are decompositions:
- 7 + 49811 = 49818
- 11 + 49807 = 49818
- 17 + 49801 = 49818
- 29 + 49789 = 49818
- 31 + 49787 = 49818
- 61 + 49757 = 49818
- 71 + 49747 = 49818
- 79 + 49739 = 49818
Showing the first eight; more decompositions exist.
