Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165822, here are decompositions:
- 5 + 165817 = 165822
- 11 + 165811 = 165822
- 23 + 165799 = 165822
- 43 + 165779 = 165822
- 73 + 165749 = 165822
- 101 + 165721 = 165822
- 103 + 165719 = 165822
- 109 + 165713 = 165822
Showing the first eight; more decompositions exist.
