Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83142, here are decompositions:
- 5 + 83137 = 83142
- 41 + 83101 = 83142
- 53 + 83089 = 83142
- 71 + 83071 = 83142
- 79 + 83063 = 83142
- 83 + 83059 = 83142
- 139 + 83003 = 83142
- 179 + 82963 = 83142
Showing the first eight; more decompositions exist.
