Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40620, here are decompositions:
- 11 + 40609 = 40620
- 23 + 40597 = 40620
- 29 + 40591 = 40620
- 37 + 40583 = 40620
- 43 + 40577 = 40620
- 61 + 40559 = 40620
- 89 + 40531 = 40620
- 101 + 40519 = 40620
Showing the first eight; more decompositions exist.
