Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30850, here are decompositions:
- 11 + 30839 = 30850
- 41 + 30809 = 30850
- 47 + 30803 = 30850
- 137 + 30713 = 30850
- 173 + 30677 = 30850
- 179 + 30671 = 30850
- 257 + 30593 = 30850
- 293 + 30557 = 30850
Showing the first eight; more decompositions exist.
