Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28632, here are decompositions:
- 5 + 28627 = 28632
- 11 + 28621 = 28632
- 13 + 28619 = 28632
- 29 + 28603 = 28632
- 41 + 28591 = 28632
- 53 + 28579 = 28632
- 59 + 28573 = 28632
- 61 + 28571 = 28632
Showing the first eight; more decompositions exist.
