Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83240, here are decompositions:
- 7 + 83233 = 83240
- 13 + 83227 = 83240
- 19 + 83221 = 83240
- 37 + 83203 = 83240
- 103 + 83137 = 83240
- 139 + 83101 = 83240
- 151 + 83089 = 83240
- 163 + 83077 = 83240
Showing the first eight; more decompositions exist.
