Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22018, here are decompositions:
- 5 + 22013 = 22018
- 41 + 21977 = 22018
- 89 + 21929 = 22018
- 107 + 21911 = 22018
- 137 + 21881 = 22018
- 167 + 21851 = 22018
- 179 + 21839 = 22018
- 197 + 21821 = 22018
Showing the first eight; more decompositions exist.
