Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30898, here are decompositions:
- 5 + 30893 = 30898
- 17 + 30881 = 30898
- 29 + 30869 = 30898
- 47 + 30851 = 30898
- 59 + 30839 = 30898
- 89 + 30809 = 30898
- 191 + 30707 = 30898
- 227 + 30671 = 30898
Showing the first eight; more decompositions exist.
