Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22438, here are decompositions:
- 5 + 22433 = 22438
- 29 + 22409 = 22438
- 41 + 22397 = 22438
- 47 + 22391 = 22438
- 71 + 22367 = 22438
- 89 + 22349 = 22438
- 131 + 22307 = 22438
- 167 + 22271 = 22438
Showing the first eight; more decompositions exist.
