Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4648, here are decompositions:
- 5 + 4643 = 4648
- 11 + 4637 = 4648
- 101 + 4547 = 4648
- 131 + 4517 = 4648
- 167 + 4481 = 4648
- 191 + 4457 = 4648
- 197 + 4451 = 4648
- 227 + 4421 = 4648
Showing the first eight; more decompositions exist.
