Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22578, here are decompositions:
- 5 + 22573 = 22578
- 7 + 22571 = 22578
- 11 + 22567 = 22578
- 29 + 22549 = 22578
- 37 + 22541 = 22578
- 47 + 22531 = 22578
- 67 + 22511 = 22578
- 97 + 22481 = 22578
Showing the first eight; more decompositions exist.
