Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22842, here are decompositions:
- 31 + 22811 = 22842
- 59 + 22783 = 22842
- 73 + 22769 = 22842
- 101 + 22741 = 22842
- 103 + 22739 = 22842
- 151 + 22691 = 22842
- 163 + 22679 = 22842
- 173 + 22669 = 22842
Showing the first eight; more decompositions exist.
