Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18622, here are decompositions:
- 5 + 18617 = 18622
- 29 + 18593 = 18622
- 83 + 18539 = 18622
- 101 + 18521 = 18622
- 179 + 18443 = 18622
- 251 + 18371 = 18622
- 269 + 18353 = 18622
- 281 + 18341 = 18622
Showing the first eight; more decompositions exist.
