Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4620, here are decompositions:
- 17 + 4603 = 4620
- 23 + 4597 = 4620
- 29 + 4591 = 4620
- 37 + 4583 = 4620
- 53 + 4567 = 4620
- 59 + 4561 = 4620
- 71 + 4549 = 4620
- 73 + 4547 = 4620
Showing the first eight; more decompositions exist.
