Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30738, here are decompositions:
- 11 + 30727 = 30738
- 31 + 30707 = 30738
- 41 + 30697 = 30738
- 61 + 30677 = 30738
- 67 + 30671 = 30738
- 89 + 30649 = 30738
- 101 + 30637 = 30738
- 107 + 30631 = 30738
Showing the first eight; more decompositions exist.
