Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22590, here are decompositions:
- 17 + 22573 = 22590
- 19 + 22571 = 22590
- 23 + 22567 = 22590
- 41 + 22549 = 22590
- 47 + 22543 = 22590
- 59 + 22531 = 22590
- 79 + 22511 = 22590
- 89 + 22501 = 22590
Showing the first eight; more decompositions exist.
