Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30804, here are decompositions:
- 23 + 30781 = 30804
- 31 + 30773 = 30804
- 41 + 30763 = 30804
- 47 + 30757 = 30804
- 97 + 30707 = 30804
- 101 + 30703 = 30804
- 107 + 30697 = 30804
- 127 + 30677 = 30804
Showing the first eight; more decompositions exist.
