Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162, here are decompositions:
- 5 + 157 = 162
- 11 + 151 = 162
- 13 + 149 = 162
- 23 + 139 = 162
- 31 + 131 = 162
- 53 + 109 = 162
- 59 + 103 = 162
- 61 + 101 = 162
Showing the first eight; more decompositions exist.
