Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83180, here are decompositions:
- 3 + 83177 = 83180
- 43 + 83137 = 83180
- 79 + 83101 = 83180
- 103 + 83077 = 83180
- 109 + 83071 = 83180
- 157 + 83023 = 83180
- 199 + 82981 = 83180
- 241 + 82939 = 83180
Showing the first eight; more decompositions exist.
