Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49842, here are decompositions:
- 11 + 49831 = 49842
- 19 + 49823 = 49842
- 31 + 49811 = 49842
- 41 + 49801 = 49842
- 53 + 49789 = 49842
- 59 + 49783 = 49842
- 101 + 49741 = 49842
- 103 + 49739 = 49842
Showing the first eight; more decompositions exist.
