Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43620, here are decompositions:
- 7 + 43613 = 43620
- 11 + 43609 = 43620
- 13 + 43607 = 43620
- 23 + 43597 = 43620
- 29 + 43591 = 43620
- 41 + 43579 = 43620
- 43 + 43577 = 43620
- 47 + 43573 = 43620
Showing the first eight; more decompositions exist.
