Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82040, here are decompositions:
- 3 + 82037 = 82040
- 19 + 82021 = 82040
- 31 + 82009 = 82040
- 37 + 82003 = 82040
- 67 + 81973 = 82040
- 73 + 81967 = 82040
- 97 + 81943 = 82040
- 103 + 81937 = 82040
Showing the first eight; more decompositions exist.
