Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 184638, here are decompositions:
- 5 + 184633 = 184638
- 7 + 184631 = 184638
- 11 + 184627 = 184638
- 29 + 184609 = 184638
- 31 + 184607 = 184638
- 61 + 184577 = 184638
- 67 + 184571 = 184638
- 71 + 184567 = 184638
Showing the first eight; more decompositions exist.
