Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17822, here are decompositions:
- 31 + 17791 = 17822
- 61 + 17761 = 17822
- 73 + 17749 = 17822
- 109 + 17713 = 17822
- 139 + 17683 = 17822
- 163 + 17659 = 17822
- 199 + 17623 = 17822
- 223 + 17599 = 17822
Showing the first eight; more decompositions exist.
