Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30826, here are decompositions:
- 17 + 30809 = 30826
- 23 + 30803 = 30826
- 53 + 30773 = 30826
- 113 + 30713 = 30826
- 137 + 30689 = 30826
- 149 + 30677 = 30826
- 233 + 30593 = 30826
- 269 + 30557 = 30826
Showing the first eight; more decompositions exist.
