Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7906, here are decompositions:
- 5 + 7901 = 7906
- 23 + 7883 = 7906
- 29 + 7877 = 7906
- 53 + 7853 = 7906
- 83 + 7823 = 7906
- 89 + 7817 = 7906
- 113 + 7793 = 7906
- 149 + 7757 = 7906
Showing the first eight; more decompositions exist.
