Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28982, here are decompositions:
- 3 + 28979 = 28982
- 61 + 28921 = 28982
- 73 + 28909 = 28982
- 103 + 28879 = 28982
- 139 + 28843 = 28982
- 193 + 28789 = 28982
- 211 + 28771 = 28982
- 223 + 28759 = 28982
Showing the first eight; more decompositions exist.
