Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42822, here are decompositions:
- 29 + 42793 = 42822
- 71 + 42751 = 42822
- 79 + 42743 = 42822
- 103 + 42719 = 42822
- 113 + 42709 = 42822
- 139 + 42683 = 42822
- 173 + 42649 = 42822
- 179 + 42643 = 42822
Showing the first eight; more decompositions exist.
