Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8162, here are decompositions:
- 61 + 8101 = 8162
- 73 + 8089 = 8162
- 103 + 8059 = 8162
- 109 + 8053 = 8162
- 151 + 8011 = 8162
- 199 + 7963 = 8162
- 211 + 7951 = 8162
- 229 + 7933 = 8162
Showing the first eight; more decompositions exist.
