Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2162, here are decompositions:
- 19 + 2143 = 2162
- 31 + 2131 = 2162
- 73 + 2089 = 2162
- 79 + 2083 = 2162
- 109 + 2053 = 2162
- 151 + 2011 = 2162
- 163 + 1999 = 2162
- 211 + 1951 = 2162
Showing the first eight; more decompositions exist.
