Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30982, here are decompositions:
- 5 + 30977 = 30982
- 11 + 30971 = 30982
- 41 + 30941 = 30982
- 71 + 30911 = 30982
- 89 + 30893 = 30982
- 101 + 30881 = 30982
- 113 + 30869 = 30982
- 131 + 30851 = 30982
Showing the first eight; more decompositions exist.
