Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2822, here are decompositions:
- 3 + 2819 = 2822
- 19 + 2803 = 2822
- 31 + 2791 = 2822
- 73 + 2749 = 2822
- 103 + 2719 = 2822
- 109 + 2713 = 2822
- 139 + 2683 = 2822
- 151 + 2671 = 2822
Showing the first eight; more decompositions exist.
