Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22586, here are decompositions:
- 13 + 22573 = 22586
- 19 + 22567 = 22586
- 37 + 22549 = 22586
- 43 + 22543 = 22586
- 103 + 22483 = 22586
- 139 + 22447 = 22586
- 283 + 22303 = 22586
- 307 + 22279 = 22586
Showing the first eight; more decompositions exist.
