Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83138, here are decompositions:
- 37 + 83101 = 83138
- 61 + 83077 = 83138
- 67 + 83071 = 83138
- 79 + 83059 = 83138
- 157 + 82981 = 83138
- 199 + 82939 = 83138
- 379 + 82759 = 83138
- 409 + 82729 = 83138
Showing the first eight; more decompositions exist.
