Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 622, here are decompositions:
- 3 + 619 = 622
- 5 + 617 = 622
- 23 + 599 = 622
- 29 + 593 = 622
- 53 + 569 = 622
- 59 + 563 = 622
- 101 + 521 = 622
- 113 + 509 = 622
Showing the first eight; more decompositions exist.
