Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4906, here are decompositions:
- 3 + 4903 = 4906
- 17 + 4889 = 4906
- 29 + 4877 = 4906
- 89 + 4817 = 4906
- 107 + 4799 = 4906
- 113 + 4793 = 4906
- 173 + 4733 = 4906
- 227 + 4679 = 4906
Showing the first eight; more decompositions exist.
